Screen goes black whenever i exit fullscreen media

[Mog]

Hi guys, encountering my first real issue with what i think is the DE, whenever i go out of full screen on any form of video media, eg: YT vids, Discord vids or even exclusive fullscreen / fullscreen-borderless games, my screen goes black for a few seconds. No more than 4 seconds, but its starting to annoy me, as far as configurations go im all stock on the DE, only changed my wallpaper. Im running a RTX 4090, could this be an indication? Never troubleshooted on Linux yet, so not sure where to start with something like this.

What’s the output of:

inxi -FGxxz

And, have you tried to replicate this in both Wayland and X11 sessions?

I have not, i don’t quite know how to change sessions on KDE.

Follow the instructions below. Bascially, log out, select Plasma X11/Xorg, log in.

@joekamprad

Nvidia … … …
Be aware and in case session is wonky change to X11 session.
The issue here is what you find on point 1. Session is using plasma what is now Wayland (new default) in case you are using auto-login you have to follow the instructions in 1. And edit /etc/sddm.conf manually, If no auto-login you can log out and change session to X11 there (bottom left).

Once done, test it to see if the issue still occurs. If it doesn’t (it probably won’t), then you know it’s very likely a compatibility issue with Wayland and Nvidia.

If it does happen, then we can troubleshoot more.

Whether it still happens or not, please let us know.

[Mog]

Thank you very much for helping me with this! It seems that it was indeed the Wayland session that was causing this, I notice that my display configuration options are much more limited within an X11 session, is this by design? There is also a significant decrease in the overall “smoothness” of the DE, moving windows around for example isnt as smooth, even with the selected 240hz option.

For example, VRR / no adaptive sync or screen tearing options, I do recall reading somewhere a while back that Wayland was much worse on Nvidia cards, and only as of late has it somewhat improved.

Yes, Wayland and Nvidia can be great for some and terrible for others. Wayland brings in some improvements to working with or utilising graphic cards better, but again, because it’s currently hit or miss with Nvidia cards, you may not be able to use it as you want/expect.

It’s getting better, though, so check things out from time to time to see if the issue has been fixed. Specifically, check when you get nvidia, kernel, BIOS, Plasma, or Wayland updates.

Any of those five updates can make a difference, and apart from BIOS updates, you are likely to have multiple updates for them each week.
