KDE Kontact Windows does not show text in dark mode

Hello everyone,

I’m having trouble using my KDE Kontact suite. When I want to see the content of an email, I do not see any text, only weird structures. However, I mark the email and copy the text to another program, that works. So I think it has to do something with the dark mode of KDE.

I’m using Kontact Version 6.3.3 (24.12.3) with KDE 6.3.4 on openSUSE Tumbleweed. Is this a bug? I mean, some days ago, it worked.

Thank you for your help.
hihu

You have Qt 6.9 ?

To inform your KDE it is best to copy the output of this command: kinfo

Your screenshot is a lot similar with the bug in Qt 6.9 in this thread:

Yes. That bug did affect the KMail app Kontact.

Let me guess @fhihu : You are using X11 and you have an AMD GPU, correct?

Thank you for your replies.

Yes, you are correct:

So the bug is already known. So I guess I don’t have to do anything, just waiting for a fix. Or should I provide more details?

Yes. The bug was opened and marked as Critical:
