? HELP NEEDED ? black screen at full screen video playback

[johnny45]

Ive got a bug issue with ubuntu 24.04 lts with vrr enabled at 144hz on my AOC C24G1A 24" Monitor

when ever i go for any video playback in full screen from the web browser , or even if i make the browser full-screen

it goes black screen no signal

2 questions

1. why is this

2. how do i fix

my browser is the flatpak librewolf

an these are the custom settings for the frame in librewolf

 

about config screen grab

 

 

the default has the same issue.

 

this black out an lose of connection happens even with apps like celluloid at fullscreen

 

enabling freesync on the monitor half way fixs as playback is visible but with heavy artifacts an micro stutters.

Does it happen with VRR disabled?

[johnny45]

no , not at all

Then it's likely this upstream issue surrounding out of range refresh rates, https://gitlab.gnome.org/GNOME/mutter/-/issues/3419.
VRR in GNOME is experimental so id expect problems, the solution for now would be to probably leave it disabled.

im running ubuntu 24.04lts on the ubuntu on wayland desktop if that makes any diff.

It's experimental in all distributions shipping GNOME that have the option available.

I don't believe it's experimental in Plasma 6 however.  If you want to try that I believe the below distros all ship Plasma 6.
