1827446 - [Wayland] Picture-in-Picture overlay remains visible after resizing window

Status: RESOLVED FIXED

(Core :: Widget: Gtk, defect)

Description

[Kestrel]

Attachment: Video of PiP overlay persisting after window resize

STR:

1. Start with MOZ_ENABLE_WAYLAND=1 on Ubuntu 22.10.
2. Open a Picture-in-Picture video and start playback.
3. Hover mouse cursor over PiP window so that it shows controls overlay.
4. Move mouse cursor to the top-left corner resize zone.
5. With overlay still visible, shrink down the window from the resize zone by moving cursor down so it ends up outside the window.

Expected:
Overlay should disappear after a short timeout while the video is playing with the cursor outside the window.

Actual:
Overlay is still visible and persists after timeout. Hover tooltip also remains visible. Have to move the cursor inside PiP window and back outside to get the overlay to timeout and disappear.

Does not happen on XWayland.
