Waking up an old thread here but I thought I'd share what I've learned.

I think I found out what caused both tearing and crashing when I used
OpenGL.
Since I changed from using xcompmgr to compton with following options

compton --backend glx --vsync opengl-swc --paint-on-overlay
--glx-no-stencil -b

I have never had a crash or tearing. Have no idea why this is but I am just
happy I don't get hung GPU anymore.
