Hey everyone, I'm facing a weird problem with fullscreen video playback on my 1440p monitor. It seems that whenever I set my Windows display scaling to 125%, videos lag terribly, with dropped frames and the GPU usage jumping to 97%. This only happens in fullscreen mode across all browsers like Brave, Chrome, Firefox, and Edge. However, if I switch to 4K resolution, the video plays smoothly, which is super baffling.
I've tried a bunch of different fixes, like changing fullscreen modes, disabling fullscreen optimizations, and messing with the ANGLE backends (D3D11, OpenGL). I even played around with browser settings and Windows DPI compatibility settings, but nothing seems to work.
I need to keep hardware acceleration on for my browsing since I use it for more than just videos, and dropping to 100% scaling makes everything too small on my display. Plus, the same issue happens when I move the browser to my 1080p monitors—and they're set to 100% scaling—until I also switch the scaling of my 1440p monitor back to 100%. It's like that 125% scaling is causing some global conflict.
I know I could switch to 100% scaling when watching videos or use theater mode as a workaround, but I'm really looking for an actual fix or if anyone else has experienced this issue. Any insight or advice would be greatly appreciated!

Have you tried disabling multi-pane optimizations? Sometimes that can help resolve hardware acceleration issues. I found a tip on it and it might be worth a shot!
Thanks for the suggestion! I gave it a try, but unfortunately it didn’t resolve the issue.
