Bug
Description
When fullscreening Firefox (e.g. F11), the window will no longer update. Moving the cursor does cause the window to update, but only for as long as the cursor is being moved.
Chromium is not affected by this problem, nor is Firefox when on my laptop's built-in monitor. This only happens when Firefox is on an external monitor. (In my case, it's over HDMI.)

Worth noting that setting misc:vfr = false or debug:damage_blink = true gets rid of the problem, but obviously neither are viable fixes long-term.
How to reproduce
- Open Firefox on an external monitor.
- Go to a page that has motion, such as one with a video or a GIF (or open a local video file).
- Fullscreen Firefox.

same issue happens for me I have also found out that the stutter on 2nd monitor only happens for specific fractional display ratios. If I set my main monitor ([email protected] or 1.666667), my 2nd monitor (1920x1080@auto) won't stutter but if I set it ([email protected] or 1.6), it will stutter
it was working before somewhere at version 0.32.x or 0.33.x but broke when arbitrary fractional display ratio is forbidden
I have also found out that the stutter on 2nd monitor only happens for specific fractional display ratios.
This appears to be the issue, or at least part of it. The freezing goes away for me at 1x scaling for the main monitor (usually 1.566667x).

The section of debug:overlay describing the second monitor stops updating when the monitor freezes. debug:damage_blink seems buggy with a second monitor, as even the primary monitor's updates aren't correctly reflected by the purple. This issue/inaccuracy goes away with the second monitor unplugged.
