[Touch-packages] [Bug 1364522] Re: Firefox crashes sometimes when using webgl with nouveau driver
I was probably wrong last year. - In [1] there are still many crash reports to Mozilla. - These point very often too to the ~GLContextGLX destructor, similar to comment #0. - Kernels are often Ubuntu kernels. - Probably just on 14.04 LTS. - Gallium 0.4 on NV46 or NV4B.

[Touch-packages] [Bug 1364522] Re: Firefox crashes sometimes when using webgl with nouveau driver
Problem could be reproduced with following graphic adapters: 01:00.0 VGA compatible controller: NVIDIA Corporation NV40 [GeForce 6800] (rev a1) 01:00.0 VGA compatible controller: NVIDIA Corporation NV31 [GeForce FX 5600XT] (rev a1) (Firefox probably blacklisted the second card for webgl, to be able to investigate on the issue I had to enable manually.) But the crash happens for the first card with default settings. As far as I could observe, Firefox creates 3 contexts, then destroys the last one but then still accesses the freed memory of the destroyed context. I believe this crash got fixed by this upstream commit: http://cgit.freedesktop.org/mesa/mesa/commit/src/gallium/drivers/nouveau/nv30/nv30_context.c?id=c092c46b27c6f6a6674e8d67fb3afdb684811819 Unfortunately this commit got only into 10.2.2. But as Trusty Tahr is a LTS release it probably will stay a long time with users using older graphics cards. Therefore I ask if this little patch could be added. -- Building package libgl1-mesa-dri like this makes the crash for me go away: mkdir -p ~/ubuntu/mesa; cd ~/ubuntu/mesa apt-get source libgl1-mesa-dri cd mesa-10.1.3 wget wget http://cgit.freedesktop.org/mesa/mesa/patch/src/gallium/drivers/nouveau/nv30/nv30_context.c?id=c092c46b27c6f6a6674e8d67fb3afdb684811819 -O debian/patches/999-nv30_avoid_dangling_references_to_deleted_contexts.patch echo "999-nv30_avoid_dangling_references_to_deleted_contexts.patch" >> debian/patches/series patch -p1 < debian/patches/999-nv30_avoid_dangling_references_to_deleted_contexts.patch dpkg-buildpackage cd .. # sudo dpkg -i libgl1-mesa-dri_10.1.3-0ubuntu0.1_i386.deb -- Other references where this bug seems to appear (just for reference): https://bugzilla.redhat.com/show_bug.cgi?id=1125339 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=661387 https://crash-stats.mozilla.com/report/list?signature=nouveau_dri.so%400x239b79 ** Bug watch added: Red Hat Bugzilla #1125339 https://bugzilla.redhat.com/show_bug.cgi?id=1125339 ** Bug watch added: Debian Bug tracker #661387 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=661387 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1364522 Title: Firefox crashes sometimes when using webgl with nouveau driver Status in “mesa” package in Ubuntu: New Bug description: Visiting with Firefox e.g. https://developer.mozilla.org/de/demos/detail/orange-slice/launch makes firefox crash.
