Linux guest: in GPU mode + Xwayland, X apps do not work and display a black rectangle

**Describe the issue**
When running Ubuntu 24.10 arm64 guest in Wayland mode with 3d/gpu acceleration enabled, the X apps do not render correctly: they only render black rectangles and start display strange artifacts as windows are moved over them.

The easiest way to reproduce is to run `xeyes`, but a number of apps will cause the same behavior, e.g. `vice` (C64 emulator) when run from terminal via `x64sc`, the `fs-uae` Amiga emulator, all Java apps running in Xwayland mode.

Thank you so much for your excellent work on UTM, it's an amazing piece of software that enables me to continue using Linux on Mac 👍 🙏

**Configuration**
* UTM Version: 4.6.4
* macOS Version: 15.2
* Mac Chip (Intel, M1, ...): M3 Max
* Guest OS: Ubuntu 24.10 arm64 in Wayland mode
* Display card: `virtio-gpu-gl-pci` with GPU Acceleration enabled
