KMail corrupted email preview?

For about a week now, KMail has had a corrupted email preview in both HTML and plain text view. This is an issue in both the preview pane and window.

Any ideas to fix this?

KDE Plasma 6.3.4-1 X11
Qt 6.9.0-1
KMail 24.12.3-1

This sounds like QTBUG-135786

Ah yes, this is exactly it. Thanks!

Some time this work :

QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu-compositing" kmail
