Screenshot of the DE with upside-down cursor

Description of problem:
Whenever I try to run a KDE Rawhide live image in a QEMU/KVM Virtual Machine with OpenGL and 3d acceleration enabled I get mouse cursors upside-down and out of pointment, which makes really hard to use the DE.

This doesn't happen with default VM settings (OpenGL and 3d accel off) or with Fedora default Gnome DE live image (with or without 3d accel).

How reproducible:
- Download a Nightly Build KDE Live image (i.e. Fedora-Rawhide-20220730.n.0 )
- Create a new VM in virt-manager to run the Live Image
- Observe that with default settings the cursors works right
- Shut down VM and change settings enabling OpenGL in Spice Monitor and 3D acceleration in Virtio Video
- run VM and observe nearly unusable DE because of upside-down and out of pointment cursors

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It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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.

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

field may be hidden. Click the "Show advanced fields" button if you do not see
