Some applications may crash on resize operations on GNOME on Raspberry Pi 4 and 400

Problem When running GNOME on Fedora 41 on a Raspberry Pi 4 or 400, you may find some applications (GTK 4-based ones) crash on window resize operations. This also includes maximizing, full-screening, and ‘snapping’ windows. Cause The story behind this bug is quite deep and involves GTK and mesa, but ultimately it seems it would not happen if 256MB of system memory were allocated to the ‘CMA’ (a mechanism for sharing memory between the CPU and GPU), as is intended to be the case. This allocation…

You can discuss the problem and its solutions here, but please note that debugging and technical feedback should primarily go to the issue trackers (e.g. Bugzilla) linked in the Common Issue, because that’s the place that developers watch, not here.

If there are any updates/changes/amendments for the Common Issue description, which you believe should be performed, please post it here.
