Subject: [libreoffice-ogltrans] Blank screen with OpenGL transitions

Date: Wed, 19 Dec 2018 16:51:58 +0300

Package: libreoffice-ogltrans
Version: 1:6.1.3-2
Severity: grave
Justification: renders package unusable

When I try to use OpenGL transitions in LibreOffice Impress, I get a bank 
screen for several seconds instead of a transition. This issue seems to be 
Debian-specific; I was trying the upstream version and it works fine.

Hardware acceleration is enabled in configuration; renderer I use is

Mesa DRI Intel(R) HD Graphics 620 (Kaby Lake GT2)

Sigh. And "just" becaus it's in an own package and that packages solely
purpose is this...  :(

  OpenGL, so 3D, so slow(er) :)

And when the actual transition should happen I get "blurry" stuff until
the next slide is there. So yes, confirmed :-(

Which does not do what you think it does. It does not to "hardware
acceleration" in the first place. It afaicr is "Use cairo".

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) (prog-if 00 [VGA controller])

here, whatever that is exactly :-)

Ah, so since 6.0.1? If you know such stuff, please mark it correctly...

That said, we don't patch OpenGL parts or parts which could possibly
affect it and don't do a "custom" splitout of this either...

So it probably some system library at fault. Or some integration, though
apparently it happens with both gtk3 and "gen"... In both cases that is
still a upstream bug (, too).

Maybe we should just stop shipping them, no one needs it.

Rene

I read it. LO upstream is quite fast on blaming upstream bugs to
distributions if it doesn't work on their shipped binaries - even if it
was a bug in their code only exhibiting on newer systems with newer
libs.

LO ships all possible (including stuff available on every Linux) libraries internally
while we aren't. Including stuff like cairo etc.

And no, I am so not going to use gazillions of (old, (security buggy at
times) internal libraries.

So still, it can be an issue of us using some (newer) system library.

Rene

OK, so I merged -ogltrans back into -impress. That makes this bug
a) "fixed" in 1:6.4.1-2 of libreoffice-ogltrans (as it's now
   a transitional package and doesn't contain anything)
b) only "important", since it definitely doesn't make the whole
   of Impress unusable but just affects the OpenGL transitions thingy.

<confession>
Yes, this is an "evil" trick to make this bug not RC anymore...
</confession>

If someone finds the cause of this it can and will be fixed, though.

Regards,
 
Rene
