Ever since at least 375.xx I get artifacts on screen after a suspend.
After a suspend-restore cycle, the display output sometimes becomes garbled, but I can still see contours of what is supposed to be drawn. alt+tabbing between a window with a glcontext open, sometimes fixes the artifacts. Changing from VT and back to Xorg also sometimes fixes the artifcats for a while, but it always comes back. The only fix is a clean reboot.
I’ve had this issue for a few months now, and it’s not getting better so I decided to try report this issue.
The log attached is from after 1 suspend cycle is performed after a reboot.
Note: In the latest release, 375.26, the background ‘noise’ color went from green to black.
