I can't replicate that here. Please get the output of drm_info from when the black bars are visible. Sure thing. A bit hard to obtain that information since entering another window or another window update can cause the black bars to disappear. I was able to obtain it by activating the command `sleep 10; drm_info > drm_info.txt` minimizing the terminal, then interacting/moving/resizing firefox window until the black bars are visible (before the 10 second sleep was up) then just waiting for the command to execute.
