Screen goes black when fullscreen videos in browsers

General system Gaming, sound and video
1

Did some googling to no avail so if you all know of another post ill hop right too it and close this.

Long story short whenever I full-screen a video, be it reddit, yt, twitch, insta, etc… The screen goes black instead of streaming the video. The sound still plays, and with Firefox and YT if I move the mouse to show the controls the video pops up but as soon as the video controls go back to sleep the video is black again.

I have tested this with Firefox and Chromium. I have not tried newer kernel than 6.6LTS. Just had this thought when I was about to post this. Will try now.

I tried to run both browsers from the command line to see what was going on but apparently they don’t dump logs while running from terminal anymore without a command? Not sure, it is new to me.

Welcome to the community! :vulcan_salute: :enos_flag:

Have you tried this in an X11/Xorg session?
Also, have you tried it with a video that is stored on your system?

Seems to work fine with X11/Xorg. Switched to Kernel Version: 6.9.6-arch1-1 (64-bit) and problem persists differently. It seems like it somewhat “settles in” after a few seconds. I did notice that my monitor source popup displayed when it was changing leading me to believe it has something to do with my display settings.

After coming to that realization I went and fiddled with some settings and tested. Turns out Adaptive Sync was the culprit.

Turning off Adaptive Sync solved the issue.
