Stellarium is glitchy when running via Xwayland
Steps to reproduce:
- Install Stellarium (e.g. via Flathub).
- Launch and wait until the main window appears
- Interact
Once the main window appears, moving around the cursor, opening/closing dialogs, will cause the UI to "blink" oddly.
Running it via Xorg does not result in the same behaviour.
I have observed this glitchy behavior when Xwayland is run from mutter, weston and kwin, but they glitchyness behave slightly different.
