Subject: bumblebee: using optirun introduces segfault in i965_dri.so

Date: Thu, 14 Jun 2018 21:31:50 +0300

Package: bumblebee
Version: 3.2.1-17
Severity: normal

Dear Maintainer,

Looks like after recent Mesa update in Sid, I cannot use optirun any
more on laptop with i7-4710HQ and GM107M [GeForce GTX 860M] as it
introduces crash for application run under it. 

Launching `optirun glxgears` makes glxgears crash:

I have read about HAVE_DRI3_MODIFIERS here:
https://bugs.freedesktop.org/show_bug.cgi?id=106910

And it works if you make the Debian package (from source mesa-18.1.2) with
the following patch (here you can get the Debian package that I have built:
http://s000.tinyupload.com/index.php?file_id=01939742983669320839):

Looks like there is much simpler workaround:

PRIMUS_UPLOAD=1 primusrun glxgears

Works for wine too.

Sadly, `PRIMUS_UPLOAD=1 primusrun glxgears` does not work any more, also segfaults:
