Bug 504149

Application: kmail (6.4.1 (25.04.1))

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.0
Frameworks Version: 6.14.0
Operating System: Linux 6.14.6-arch1-1 x86_64
Windowing System: Wayland
Distribution: Arch Linux
DrKonqi: 6.3.5 [CoredumpBackend]

-- Information about the crash:
When starting kmail (or kontact), it crashes when the window is maximized or resized (could test something else).

This started after the update to qt6-webengine 6.9 (downgrading to 6.8 fixed it, but can;t do it anymore because of new libxml2 version requirements)

This only seem to happen on my computer that has an NVidia GPU (NVIDIA Corporation GA102 [GeForce RTX 3080] (rev a1)) with the vulkan-nouveau driver.

When it starts as a small window, the email content part is not shown (only mail list and accounts). If I start increasing the window's height, it looks like the crash happens exactly when the email content view becomes visible, therefore using the qtwebengine to show the email.

Let me know if you need more details.

The crash can be reproduced every time.
