Relevant logs, screenshots, screencasts etc.
- Screenshot
- I have AMD laptop with 5800H+6700M (MSI Delta 15 to be exact)
- The issue doesnt happen on internal monitor (testufo.com said 240FPS which is make sense because i have 240Hz internal monitor). Only when its connected to external monitor
- Any display output connected directly to the 6700M (So, HDMI and DP have same issue)
- This does affect game that runs AT ANY FPS (This means the stutter still there even tho the games runs 100FPS+ and it still feels like below 60FPS)
- To test this make sure the firefox running under wayland not xwayland, otherwise testufo.com gonna said 75FPS
