Full-screen window setting resets upon workspace switch

Hi all,

I posted this issue previously here: https://forum.xfce.org/viewtopic.php?pid=76794#p76794, which was confirmed by another member.

After upgrading to Xubuntu 24.04 from 22.04, I encountered an issue with XFCE. The setting of a window being in full-screen (using the "Fill window" command) is reset to its previous tiling setting when switching between workspaces. Unfortunately, I do not know the exact versions of XFCE components before the upgrade where it worked well.

Current version:

$ xfce4-session --version xfce4-session 4.18.3 (Xfce 4.18)

Steps to Reproduce:

Bind the following Window Manager actions to specific keys:

• "Fill window" (maximize/full-screen) to a key/button.
• "Tile window to the left" to a key/button.
• "Switch to Workspace 1" to a key/button.
• "Switch to Workspace 2" to a key/button.

Detach a random window from any tiling (ensure the window is in a non-tiled state).

Use the "Tile window to the left" button/key.

-> Switching between workspaces works as expected; the window stays tiled to the left.

Use the "Fill window" button/key on the tiled window.

-> After switching to another workspace and back, the window no longer stays filled (maximized). It resets to the tiled state (left-tiling) instead of remaining full-screen.

Expected Behavior:

The "Fill window" setting (full-screen/maximized) should persist when switching between workspaces. It should not revert to the previous tiling configuration.

Let me know if you need anything more.
