I’ve updated the issue to also cover 2276102 – Severe graphical corruption in anaconda (Fedora installer) when running on VirtualBox with 3D passthrough enabled , which is also an issue with corrupted display on VirtualBox with 3D passthrough but doesn’t seem like it can be the same issue, as anaconda is not a GTK 4 app. I also added a suggestion to use vbox’s “VBoxSVGA” graphics adapter instead of the default “VMSVGA” if you have trouble with “VMSVGA” with 3D acceleration disabled (I found that KDE won’t start in this config, no idea why not).

Thanks, Adam.

Is no work on this happening at all? All linked issues (and the ones linked from them) have stalled, except one update on gtk4 (but the assumption that it might have been fixed did not apply).

I don’t see any activity on the Mesa ticket, or in Mesa’s release notes.

Disabling 3D acceleration is not really a desired workaround…

Cheers,
Moritz

You can try to ask the upstream developers in their tickets. They most probably don’t watch this thread.
