Due to broken operating system support for my graphics card, I need to use blender-softwaregl to get a usable interface. I'm running Debian GNU/Linux unstable.

Things used to work fine until I upgraded today from blender-2.74-linux-glibc211-x86_64 to blender-2.76-rc3-linux-glibc211-x86_64; blender itself still starts (but has the interface problems), blender-softwaregl segfaults.

/tmp/blender.crash.txt says:

When starting it with valgrind, I get these errors:

Due to broken operating system support for my graphics card, I need to use blender-softwaregl to get a usable interface. I'm running Debian GNU/Linux unstable.

Fantastic… I can confirm this here (debian64 testing) with 2.76RC3, but not with own build of current master.

@Sergey, @ideasman42, ideas?

Bastien Montagne changed title from ~~blender-softwaregl no longer works~~ to blender-softwaregl crashes in 2.76RC3

This is caused by 86e6d66 done by @campbellbarton. Seems it's in fact crucial to have context initialized before calling glewInit().

The whole logic around check GLXEW_ARB_create_context seems to be broken in fact. Even with proper nvidia driver here first time drawing context is being initialized GLXEW_ARB_create_context is set to 0 here, but when second window is creating GLXEW_ARB_create_context is set to 1.
