If you boot a Fedora 40 Final Workstation or KDE live image in VirtualBox with 3D passthrough enabled (using the "VMSVGA" adapter, which is the only one for which 3D passthrough seems to work), then run the Fedora installer, it shows extensive visual corruption, to the point of unusability. See attached pictures. This seems to be different from https://bugzilla.redhat.com/show_bug.cgi?id=2274930 (but may be somehow related). anaconda uses GTK 3, not GTK 4 (via gobject introspection). Other GTK 3 apps (I tested firewall-config and Firefox) don't seem to be affected. With 3D passthrough disabled, anaconda seems to work fine. I also did not observe this bug on VMware, it seems to be specific to VirtualBox. I was testing on a Windows 11 23H2 host using Intel graphics, with the latest upstream VirtualBox as of yesterday.
