Subject: freeplane: Visual corruption after scrolling mindmap right - openjdk issue?

Date: Sat, 21 Apr 2012 11:34:31 +0100

[Message part 1 (text/plain, inline)]

Package: freeplane
Version: 1.1.3-2
Severity: normal

Dear Maintainer,

Open any mindmap, scroll right and the visible mindmap area visually corrupts. 
The mindmap seems to be rerendered on certain cues, such as collapsing and expanding nodes - 
using Tools -> Preferences -> Behaviour page -> Selection Method: Center selected nodes works around
most of the problems as using the keyboard to navigate causes the map to be repeatedly rerendered.

This issue is probably openjdk-based as it used to happen to Freemind when I used it, and in Freemind,
Freeplane and jEdit the file browing dialog's contents corrupt in a similar way. Reporting it here
as Freeplane is the program I use most by far - please say if I need to log this against openjdk.

I have attached screenshots showing the corruption, and I can make many more if needed (in the dialog's
case I scrolled back and forth a few times, the corruption seems additive).

Thanks

Package: freeplane
Version: 1.1.3-2

This bug is being tracked in 
https://bugs.freedesktop.org/show_bug.cgi?id=50850 - the real workaround 
is to pass '-Dsun.java2d.xrender=True' to java. For the benefit of other 
radeon freeplane users, I have attached a diff to /usr/bin/freeplane 
that adds to the defines variable that is already in use.

hi Omega,

thanks for the patch. Sorry for the delay: I just picked up the
freeplane 1.2.x package about a month ago, and I also need to update
simplyhtml and libjsyntaxpane-java for the freeplane package to work,
so I was quite busy with this ;-)

I am also working upstream on freeplane => so I have some questions
regarding your patch:

- Can we generally apply this patch or could it break something else in
  some cases?

- What is your experience with OpenJDK? Does it work properly (with this
  patch)? Now that OpenJDK7 has (almost) the same codebase as OracleJDK7
  (that's what the OpenJDK folks told me), I think we should try to
  support it.

Thanks and Best Regards,

Very sorry about the delay - I didn't get your email.

So far the change has simply lead to slow graphics rendering in 
freeplane (interestingly when you get to the second/third line of a node 
it suddenly speeds up mind), but without corruption.

There is a separate failure where freeplane suddenly ignores all 
keyboard input, but I later confirmed this also happened under the 
normal graphics engine, so shouldn't be related (I can report this bug, 
but there is nothing useful I can say about it - I have to restart 
freeplane at this point).

Currently I use Eclipse, RSSOwl, and now I2P - OpenJDK seems to behave.

Aside from the strange keyboard issue, the other major failure I've seen 
is with Open Wonderland (http://openwonderland.org/) - the 
game/experience is unusable, I'm told due to 
http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=568 - you can see 
the long thread I had here - 
https://groups.google.com/forum/?fromgroups=#!topic/openwonderland/-c3P211bjGI). 
This of course is non-essential.

You could try to update to 1.2.23, but I don't know whether that would
fix it (probably not).

There was an interesting reply:
  https://bugs.freedesktop.org/show_bug.cgi?id=50850#c13

which states that the XRender pipeline (-Dsun.java2d.xrender=True)
also causes problems (this time when scrolling _vertically_ ;-)
  https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/1101348

The vertical scrolling bug is reported to be fixed in openjdk-8:
  http://mail.openjdk.java.net/pipermail/xrender-dev/2013-January/000050.html
=> I guess that means we don't get a fix for openjdk-7, but I will ask
on Debian-java (since it's patched on Ubuntu already).

So, to repeat this: the solution is to pass -Dsun.java2d.xrender=True to
java, which can be done by modifying 'JAVA_OPTS' in /usr/bin/freeplane
for the 1.2.23 Debian package (or modify 'defines' for the 1.1.x
package). But that might create problems as well, so you should only use
it if you have visual corruption and I shouldn't include it in
/usr/bin/freeplane of the Debian package at least until the xrender
pipeline is fixed in OpenJDK7 of Debian.

That's good to know, I am also using OpenJDK7 in the mean time and have
no major problems.

OK, will wait till that and its dependencies hit testing. Not looking 
forward to it if this upgrade will visually trash my mindmaps though ;) 
(At work I tried a recent version and they'd changed the way things were 
rendered, making it a lot less space efficient etc - went straight back 
to the 'current' version).

I was imagining I'd need to get C++ and Java progression to fight the 
keyboard issue.

You will have to re-apply the change (-Dsun.java2d.xrender=True) to
/usr/bin/freeplane (see above).

Since it might not be a Freeplane issue, I cannot promise that your
keyboard issue gets better (or even that it doesn't get worse) :-/ But
if it's a reproducible Freeplane issue, then Dimitry will probably (at
least try to) fix it.

Do you refer to 1.3.x vs 1.2.x or 1.2.x vs 1.1.x?

Anyway, IMHO this is the price for high level java programming and a
rich feature set. Or are you referring to "screen space"?

Does the issue also occur with other Java software?

I have tried to make a test case to reproduce it, but its not happening 
- both fast node creation and node moving hasn't triggered the problem 
in a new or old mindmap (my experience with the issue is its pretty 
non-deterministic, but at times it hits frequently - i.e. happens, 
restart freeplane, happens again in a minute).

The problem started at some point last year, here are my notes up until 
February, where I gave up tracking it:

30.12.12: Just had my first failure under OpenJDK v7 - have to assume 
its Freeplane's problem.
08.02.13: Seems to be more easily triggerable when I am using a chord 
with the keyboard - e.g. Cntrl + Up/down to move nodes up/down etc. Had 
this twice quickly in a row when this happened.
12.02.13: Happened repeatedly whilst I was making C mindmap Language 
data types char*/string escapes nodes.
15.02.13: Probably happens if you press a key between node creation and 
finalisation - i.e. create a node or type text into a node and enter 
then press another key before the node is 'fixed'.
27.02.13: Search on 'sizeof' in C programming mindmap - a few Cntrl+Gs 
leads to this issue

I had hoped to learn Java and then hook into keypresses - some 
completely clueless notes:

====================================================================

grep -iInr 'getNodeKeyListener'
src/org/freeplane/view/swing/ui/UserInputListenerFactory.java:192: 
public KeyListener getNodeKeyListener() {
src/org/freeplane/view/swing/map/NodeView.java:1126: 
mainView.addKeyListener(userInputListenerFactory.getNodeKeyListener());
src/org/freeplane/core/ui/IUserInputListenerFactory.java:58: 
KeyListener getNodeKeyListener();

These are under the freeplane source directory. 
'src/org/freeplane/core/ui/IUserInputListenerFactory.java' looks to be 
the initial interface which ties Java functionality (KeyListener) with a 
method. It looks like 
'src/org/freeplane/view/swing/ui/UserInputListenerFactory.java' might 
allow me to insert code on keypresses, but theres nothing about keypress 
events, just method calls - so it might not be doable without creating 
my own KeyListener method?

Screen space - hence visual comment. I'll stop here now since its been 
some months since I tested and my memory is hazy - quick testing right 
now on the work Windows machine shows that nodes are no longer bubbles, 
automatic formatting style appears to have changed, icons are not on the 
side closest the centre (which is where my eyes scan), etc etc... I 
guess all that is just a project to fight to get the appearance back to 
normal. I also remember having to mess with DPI to get a similar size, 
but it looks OK now in this test.

I havent seen this in anything else - freeplane is by far my most used 
Java program, but I use Eclipse + PyDev fairly often so I should have 
had this happen a few times by now if the problem was more widespread.

Thanks!

I talked to Dimitry, the project lead, about the issue. _Roughly_ it's
like this:

- there is an EventQueue to make sure that the input order is preserved
- an EventBuffer/KeyEventDispatcher waits for the component to get focus
  or for an ESCAPE key press
- There is only one Thread, so it's not a multi-threading issue.

=> *a workaround is to press ESCAPE in this case :-)*

Dimitry tried hard to reproduce this with a fixed set of steps, and he
didn't succeed, so it may be hard to do :-(

I am a Java dev myself, and I don't know how to fix this. I think you
have to dive really deeply into swing _and_ into the freeplane codebase
(like Dimitry does) in order to fix this.

I think you can hide every sub-window in Freeplane. Freeplane 1.3.x (not
yet released) will be even more flexible as every subwindow can be
arranged independently.

If you have a question concerning the new features that you can't figure
out yourself, you can post here:

According to the above, the keyboard issue is not a JDK issue, but
rather a swing/freeplane issue.

Excellent, a workaround! I'll be looking forward to the next instance 
now. I'm grateful for Dimitry's efforts!

Sorry to cause such trouble - I'm due to get C++ progression hopefully 
within a few weeks, so maybe I'm 0.5y away from reading into Java. Then 
at least I will be able to add debugging code to prove what is/isn't 
happening.

Sounds like more of a hope for me than fighting OpenJDK 7!

Now that we've got the two workarounds, do you think we can close this
bug? You can open a new report if you have problems (with 1.2.23).

Have just upgraded - just for reference, have attached a before and 
after on a random mindmap - all my mindmaps use automatic formatting, 
which appears to be broken/changed now.

The bug finally happened again yesterday - ESC didnt work. Alt+F4 does 
work though - so the window manager (xfwm4 from XFCE4) gets keystrokes 
OK at least. This is a different bug from the one I originally reported, 
so it is fair enough to close this and I'll open a new one when the 
keyboard issue recurrs with the latest Freeplane.

I'm not sure what's happening here. If you want to find out, then post
here:

Package: freeplane
Version: 1.2.23-1

The situation has now degraded again... I opened a mindmap today, and 
now with the software rendering, ends of words are disappearing! See the 
attached splash and new mindmap screenshots!

Any idea where I should report this? Its clear changes are being made in 
the Java setup without testing.

Going back to hardware rendering now - I can work around the horizontal 
scroll corruption with 'Center highlighted node' somewhat.

I don't think this is specific to Freeplane, it looks more like a
general openjdk issue.

If it persists with the suggestions (see below!), you can ask at the
xrender mailing list (since it failed with -Dsun.java2d.xrender=True),
see here:
  http://sourceforge.net/apps/phpbb/freeplane/viewtopic.php?f=1&t=681&p=3364&hilit=xrender#p3370

This looks like you're still using OpenJDK6! You should definitely try
openjdk-7:
  http://packages.debian.org/search?keywords=openjdk-7-jre&searchon=names&suite=all&section=all

You can switch to openjdk-7 by using (on my i386 jessie system):

$ update-java-alternatives --list
java-1.6.0-openjdk-i386 1061 /usr/lib/jvm/java-1.6.0-openjdk-i386
java-1.7.0-openjdk-i386 1071 /usr/lib/jvm/java-1.7.0-openjdk-i386
java-6-sun 63 /usr/lib/jvm/java-6-sun
java-gcj-4.6 /usr/lib/jvm/java-gcj-4.6
java-gcj-4.7 /usr/lib/jvm/java-gcj-4.7
$ update-java-alternatives --set java-1.7.0-openjdk-i386

If that doesn't work, you could try a 32bit- or an Oracle-JDK.

Now this was a WTF moment. I've already said that I'm using OpenJDK7 
earlier. So, I investigated how the bug script runs, and how freeplane 
works out the Java command - the java-wrappers package is responsible 
for JAVA_CMD, and this returns the v6 runtime currently.

Luckily for me I pay attention to what updates day to day (I read the 
changelogs every time) - that package recently upgraded to 0.1.26 - I 
installed the 0.1.25 version, and suddenly JAVA_CMD returns the correct 
v7 runtime! Bugs everywhere!

Running freemind again with the software rendering with the correct v7 
runtime is fine - so this is just an old irrelevant bug in OpenJDK6.

I will report the bug I have discovered against java-wrappers now, and 
uninstall the v6 runtime since its probably no longer needed.

Thanks for your help - I would not have suspected something messing 
around with my runtime version (this was configured at v7 by Debian 
alternates months ago).
