Thanks. That is a very helpful screenshot. It appears that only recently
changed widgets/actors are rendered correctly. So this suggests a bug in
mutter's buffer age logic, or the graphics driver.
Can you please:
1. Run 'lspci -k' and attach the output.
2. Run 'dmesg' (after the problem has occurred) and attach the output here.
