Re: Weird graphical glitches bug with gdm3 and gnome on stretch
Interesting... My system seems to be worse than yours, as it crashes outright
rather than producing inconsistent behavior. I also use radeon, but don't know
if that issue is hw-related.
Try booting an old 3.* kernel, if you still have one. That restored my
system's reliability. Check dmesg differences between kernel 4 and 3.
I'm no kernel expert. I'm seeking help myself, but the "Chevrolet users'
support group" doesn't seem to be much responsive these days...
