Description Adam Williamson 2024-04-19 18:09:31 UTC 
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.

This message is a reminder that Fedora Linux 40 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 40 on 2025-05-13.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '40'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 40 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Fedora Linux 40 entered end-of-life (EOL) status on 2025-05-13.

Fedora Linux 40 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
