Appearance of message pane

Upon waking up from sleeping the message pane is frequently not repainted properly - it's been like this for ages and ages. Changing message gets it fixed.

Are you using NVIDIA binary drivers?
Comment 2 davidblunkett 2019-12-24 14:41:52 UTC
Yes - wouldn't be that surprised if it is the problem but it only seems to affect kmail...
Comment 3 Christoph Feck 2019-12-25 03:09:03 UTC
It should affect all OpenGL applications, except those where developers already added driver-specific workarounds. KMail uses OpenGL via QtWebEngine.
Comment 4 Christoph Feck 2020-01-15 08:10:30 UTC
The workaround needs to be made in QtWebEngine, or ideally the NVIDIA driver fixed to not have this issue in the first place.
