I had the exact issue. My monitors were different resolutions, so I scaled my 4k display so it matched my 1440p monitor which was like a 175% increase. Linux doesn’t seem to like fractional scaling, and it worked normally when scaling was set to 200%.
YouTube videos were still choppy though. Turns out the ambient mode on videos was causing that
Yeah this is by design. Beats the alternative of having every starlink satellite ever launched hanging around low Earth orbit long after it stops working.
