Xorg randomly restarts when you enable __GL_SHARPEN_ENABLE=1 and __GL_SHARPEN_VALUE=40
For example. Launch steam with this and then start some openGL game on it. It restart X. There are no messages in dmesg nothing in Xorg logs either. just randomly X restarts. I have no idea how to debug it better.
To reproduce this issue. Try launching multiple things with SHARPENING ENABLED, will cause the X crash more likely.
Say a browser with it and some OpenGL game.
