Hello, I didn't have this bug before (with Mesa < 10) but now, when quitting Cairo-Dock, I have a crash in intel_query_dri2_buffers. I'm joining some useful informations from GDB. Regards, Matt DistroRelease: Ubuntu 14.04 Package: libgl1-mesa-dri 10.0.1-1ubuntu2 Uname: Linux 3.13.0-3-generic x86_64

I can reproduce this with origin/10.0, however it seems fixed in origin/10.1 and master. It crashes because fb is 0x0, bisected that following commit fixes this: --- 8< ---- commit 70e8ec38b55e71144ce3ed055e7da30c330c716b Author: Kristian Høgsberg <krh@bitplanet.net> Date: Wed Feb 5 11:43:58 2014 -0800 glx: Pass NULL DRI drawables into the DRI driver for None GLX drawables --- 8< ---- as a sidenote to developers, this is not related to the crash but there's following errors happening now and then from cairo-dock: Mesa: User error: GL_INVALID_OPERATION in glFramebufferTexture2DEXT This happens because glFramebufferTexture2DEXT is called with texture 0 bound.
