I have the same problem, already for some months now (on Manjaro).

Comment 2 Geert Janssens 2024-10-23 08:37:15 UTC

In GnuCash we experience similar issues in the display of reports. The rendering is done by WebKit and apparently there are some incompatibilities between some versions of webkit and some NVidia driver versions.

The workaround for GnuCash is to start the application as follows:
WEBKIT_DISABLE_COMPOSITING_MODE=1 gnucash

Perhaps the same workaround works for Kmail ? What happens if you start kmail as follows:
WEBKIT_DISABLE_COMPOSITING_MODE=1 kmail

Comment 3 Laurent Montel 2024-11-22 19:59:42 UTC

is WEBKIT_DISABLE_COMPOSITING_MODE=1 kmail works ?

Comment 4 Thorben Kaufmann 2024-11-23 08:22:51 UTC

Moved from Fedora to TuxedoOS.
Will check this if I get KMail running on this distro at all.

If someone has a running setup at hand: PLEASE TAKE OVER the test!

THNX!
