Demo Video

Steps to Reproduce:

1. Open an MKV video
2. Activate and deactivate full-screen mode multiple times (by pressing F) until some window widgets disappear.

Actual Results: Some window widgets are not rendered properly.

Expected Results: Everything is rendered properly

Versions:

• celluloid 0.23
• mpv 0.34.1
• gtk4 4.6.4
• gnome-shell 42.1

Additional Information:

• Desktop Session: GNOME (Xorg)
• OS: Arch Linux
• Clapper also has this issue, but it fixes itself after 1 sec, so it's not a big problem.
• GNOME Videos does not have this problem at all. Entering/exiting full-screen is smooth and without issue.
