Weird Multi-Monitor "bug"?

Hello there,

I’ve just now installed Garuda Linux Gnome Edition and noticed something strange.
I’m using two montiors and whenever I touch the right side of my second (right) montior. All displays move a little bit to the left.
I can do this however long I want until the window/workspace that previously was on my second screen, now is on my main screen.
The Workspace/windows I had on my main screen got pushed out of the display to the left.

I’ve made a full screenshot here:
Imgur

In which you can see that there appears to be a third screen which is just entirely black. This would also explain the “Unknown Display” I see in my Settings here:
Imgur

Sadly I can’t make a video or anything related to better showcase the issue since the displays are being moved as a whole, so you wouldn’t notice in a video.

Is there anything I can do to resolve this issue? Or is it some kind of strange “feature”?

Hi there, welcome to the forum.
Unfortunately the only thing I can say at the moment is that the described behaviour reminds me of this thread, unfortunately unsolved.
I hope the suggestions there, using nvidia-settings, the auto configuration, xrandr or a xorg.conf can help…

So as suggested in that previous post I’ve looked into the Nvidia-Settings (since I’m not using KDE).
Under “X-Server Display Configuration” I found an option called “Force Composition Pipeline” which when checked, resolves the issue I were having.
