Created attachment 90917 [details] dmesg I am using i3wm and sometimes I got some problems with gpu. I am using =x11-drivers/xf86-video-intel-2.99.905-r1, but earlier I was using 2.99.906 and I got artifacts, and gpu hung was more often. If I turned off tearfree function, the problem didn't occurred I think. I have: kernel 3.13.0-rc4, i5 2500k with hd 3000 x11-drivers/xf86-video-intel-2.99.905-r1 don't know if this is relevant since i3wm is not using mesa, but: OpenGL version string: 3.0 Mesa 10.1.0-devel (git-f9cfe5c)
