Wayland VMs freeze using QXL graphics

[Daniel van Vugt]

Using QXL graphics in a VM (the default for GNOME Boxes), the desktop freezes in Wayland sessions for long periods of time. I think mostly whenever I try to interact with an app window? If I'm only interacting with the shell then it doesn't freeze.

First noticed in 22.04 and continues now after upgrading to 24.04.

Logging into a Xorg session avoids the issue.
