The issue is stll happening on Wayland. Running kmail (or kontact) with QT_QPA_PLATFORM=xcb works but it is a little disappointing that ther ehasn't been any progress on this in years.

I confirm the problem. 

Not that before crashing, the mail pane on the lower right part stays black (see the attachment). I don't know if the problems are related. I can open another issue if needed.

Comment 5 Rainer Finke 2020-10-19 09:49:03 UTC

It's the same issue for me. Even if you remove the mail preview pane, kmail is not usable on Wayland, it doesn't directly freeze but there are many glitches.
