SUMMARY

Bit of an odd one. When watching a full screen Youtube Video, the mouse is smaller at rest. When you move the mouse, it becomes the correct size. It also makes the picture shift/jump a pixel (or two). Might be a fractional scaling thing? I have two 1440p monitors, and using a factor of 150%, and using Firefox native Wayland. 

STEPS TO REPRODUCE
1. Open YouTube Video in Firefox
2. Move mouse
3. Notice mouse size changes, and video jumps slightly

OBSERVED RESULT
Cursor changes sizes, and video jumps/shifts.

EXPECTED RESULT
Cursor should be the system setting and not change. Video should not move/jump.

Additional comments:

Could very well be Firefox itself, sure is certainly a bit of a paper cut on Wayland.

Cannot reproduce with Plasma Wayland 6, Firefox in native Wayland mode, and 200% scale.
