Having occasional Kodi GUI lockups where Estuary GUI goes blank (just the standard Estuary background colour, nothing on top), not easy to find way to repeat this lock-up.

Remove the overclock first, just to rule that out.
Assuming kodi is still running, but hung, I think if you run:

Code:

killall -SEGV kodi.bin

You will get a backtrace in ~/kodi/temp which may have some clues in.
