Issue: "Quick Tile Window to <Position>" is broken for replicated windows across virtual desktops in a multi-monitor setup

Hi all,

I’ve run into a problem related to replicated windows using the “On all desktops” pin across multiple virtual desktops in a multi-monitor setup.

TL;DR: The “Quick Tile Window to ” feature (Meta + Arrow key) doesn’t work correctly for windows pinned to all desktops when using multiple monitors and virtual desktops.

After updating my Fedora system, I noticed a large KDE Plasma 6.4 update. Everything seems fine in general, but my window arrangement behavior no longer works as it used to.

My Setup:

  • 3 monitors
  • The center monitor always shows a unique window per virtual desktop.
  • The side monitors are configured to show the same windows on all virtual desktops (using the “On all desktops” option).

Previously, when I repositioned or tiled a window using Meta + Arrow keys, those window positions would stay consistent across all desktops. Now, that’s no longer the case.

Steps:

  1. I log into my system.
  2. On one virtual desktop, I arrange my windows using Meta + Arrow (Quick Tile).
  3. Then I open Grid View (Meta + G), right-click the windows, and set them to appear on all desktops.

Expected behavior:
The window layout should remain exactly the same across all desktops.

Actual behavior:
In Grid View, everything looks fine, but when I switch between virtual desktops, the windows on the side monitors become slightly misaligned or resized.

Interestingly, if I manually align and resize the windows before replicating them across desktops, everything works as expected.

So it seems like there’s a regression or bug where Quick Tiling doesn’t correctly propagate to replicated windows across desktops in Plasma 6.4.

Anyone else seeing this behavior?

Thanks in advance!

Well KWin in Plasma 6.4 changed the not-quick-tile tiling to be per-screen.
This might explain this regression, although the two-Tiling style (QuickTiling Meta + Arrow, Shift + move/Meta+T) are supposed to be distinct.

I don’t think I fully understand, especially this “Shift + move/Meta+T” that you are referring to, but I guess this is an issue that people are aware of. I mean I can get around this by manually repositioning and resizing them, but I just don’t understand why quick tiling shortcuts are not seen as a similar operation.

Hi - it looks like this behavior has been reported through the KDE Bugtracking System: 505684 – Windows on multiple virtual desktop don't sync position and size

If you have diagnostic information that’s not already in that report, adding that in a comment would be helpful :slight_smile: Otherwise, you can add yourself to the CC list in Bugzilla to get email notifications whenever new comments are added, or the status is changed. Making sure the “Add me to CC list” option is checked, then choosing “Save Changes”, will add you:

A, it’s good if it’s acknowledged. I can live with it for the moment and I can wait a fix, so thank you for pointing this issue out.
