Comment 1 caulier.gilles 2024-08-26 03:02:06 UTC

It's clear. I crash in the EGL plugin of NVIDIA driver used by Qt to render contents with OpenGl.

Can you reproduce the crash with the 8.5.0 pre-release AppImage that we provide here :

The 8.5.0 prerelease AppImage works correctly and does not show the same crash.  Thanks!
