Window opening on dual screen

[LinuxHeki]

(1) Issue/Bug Description:
After an update (3 - 7 days ago) broke window opening on dual screen setup (just when you have tiling enabled). New window will always open on screen with already opened window. That happens also with Minecraft full screen mode. If I have opened Discord on one screen, Minecraft on other when I switch Minecraft to full screen mode it will open it on screen with Discord.
If I close Discord it will open it on the right screen.

(2) Steps to reproduce (if you know):
Open an app (browser), move it to any monitor, open another app (terminal) and it will open where another window is.

(3) Expected behavior:
Open new window / full screen mode in monitor where the mouse is / window is.

The update may have been this PR: #1171

New window will always open on screen with already opened window.

This, in itself, is expected behavior.

That happens also with Minecraft full screen mode. If I have opened Discord on one screen, Minecraft on other when I switch Minecraft to full screen mode it will open it on screen with Discord.

This sounds like the Minecraft window is "closing" and then the full-screen window is opening, although the transition doesn't quite look like that. I can recreate this with Minecraft, but it doesn't happen every time. I can't recreate it with Firefox.

When I'm seeing this happen, it seems to happen right after I change which display Minecraft is on; if I un-fullscreen and re-fullscreen, it goes onto the correct display. I'm also seeing it happen just as often (or more often) in the reverse direction, where I move the window from the external display onto an internal display with another window, and it full-screens onto the external display with no other windows.

Minecraft 1.17 doesn't switch screen, just Minecarft 1.8 (and probably some other versions which I didn't tested).

[LinuxHeki]

Minecraft (1.8) doesn't move to other screen if there is a floating window or full sized window, it must be tiled window to move there.

I also have this problem, its super annoying since i have discord and spotify open on my second screen and when nothing is open on my main screen the new window always goes to the second screen.
Please for the love of god change this, this is atm an absolute deal breaker to a otherwise almost perfect tiling extension

New window will always open on screen with already opened window.

This, in itself, is expected behavior.

Although this is (I think) consistent with the normal window opening behavior (open windows close to the focused one) it feels counter intuitive to me in the case of an empty primary monitor. For example when I switch to a new workspace (workspace disabled on secondary screen) and open a new window, I expect it to appear on the empty primary screen. Also I often have youtube or spotify on my secondary screen and as soon as my primary screen is empty my windows spawn on the secondary screen and I always have to move them over.

I think the default behavior of gnome to spawn windows on the screen where the cursor is may be problematic because of the keyboard focus of the tiling extension. Another approach would be to always spawn windows on the primary screen when it is empty (that would get it right in almost all of the use cases for me). Or maybe there is a way of telling if a window has explicit or implicit focus (did I move to it/click on it or did it receive the focus because other windows were closed) and make a decision based on that.
