STEPS TO REPRODUCE
1. Open a site that uses WebRTC like https://mozilla.github.io/webrtc-landing/gum_test.html
2. Press "Screen capture"
3. Select an XWayland window.
4. Observe the corrupted picture or observe Firefox crashing.

OBSERVED RESULT
The picture being shared is corrupted, or Firefox crashes.

EXPECTED RESULT
The picture should not be corrupted.

I've just now noticed this is also reproducible on OBS Studio when capturing an XWayland window.

Something seems to have fixed this, as I can no longer reproduce the problem. I'll close it.
