I tried everything again from the beginning, and I _can_ reproduce this with mutter 42.9 and gnome-shell 42.0. So I think you're right - this is probably a mutter bug. When I was testing initially, I relied on the built in chrome 'relaunch' button, which does not give a full clean restart. I have to fully restart the application for the bug to manifest (after re-enabling hardware acceleration). I tried to downgrade mutter to confirm that this package was the problem, but I can't go all the way back to v42.0 without apt trying to remove a whole bunch of critical packages. Unfortunately, I couldn't find v42.5 in my local cache or the repositories, either, to test with. Maybe you have a better suggestion that I could do to try and isolate the offending package? > Also can you find any other app affected? I haven't been able to reproduce this with any other applications, though I don't really use anything that stresses the GPU (likes games and such).
