Problem just started happening within the last few days. No major system changes that I can think of other than some 'live-patches' being reported as updated...
Only appears to happen in Chrome (so maybe I should report it there?) as other application don't seem to display the same glitchiness.
Appears I have to stop all instances of chrome to clear it (or of course, restart the machine)
Thanks!

I think this might be related to bug 1855757. If so then a similar fix may be needed in Chrome, OR it might be another bug in Mutter (gnome-shell).
