Screenrecording of the bug

SUMMARY
When I open KMail and want to read a mail, the panel containing the mail is missing and I can see the Desktop Background (see the attached video). Also, when the windows is moved it creates a "trail" (i don't know if there is a better name for that, can also be seen in the video).

STEPS TO REPRODUCE
1. Open KMail
2. Open Mail
3. Move Window

OBSERVED RESULT
I cannot read the message and have visual bugs

EXPECTED RESULT
I should be able to see the Message

Comment 5 marek-kochanowicz 2025-04-26 15:47:45 UTC 
This is not actually strictly KMail bug but QT webkit as it seems. For instance Zeal has the exact same problem in it's own web view.
