Youtube Playback choppy / low frame rate in DEFAULT view only

Device: Surface Pro X SQ2 OS: Windows 11 Home for ARM (Up-to-date at time of writing) Firefox Version: 125.0.3 (AArch64 up-to-date at time of writing)

I am having an issue with Firefox and video playback, specifically on YouTube. When I play a video in default view mode, the playback is super choppy / low frame rate. When I change to theatre view or full screen, playback works perfectly.

I've tried incognito windows and troubleshooting mode with no improvement.

Microsoft Edge works fine.

Not sure where to go from here.
