Playing videos in Firefox Wayland stutters in the overview
STR:
- play a (e.g. youtube) video in FF with Wayland backend (
MOZ_ENABLE_WAYLAND=1
) - open the overview
OR:
- the video only updates when GS does a repaint, e.g. triggered by other apps or moving the cursor etc.
This may also be Firefox bug or, more likely, a Mutter one.
