Description Mufeed Ali 2020-03-31 05:02:08 UTC

SUMMARY
On a Plasma Wayland session with Latte using the Unity layout or a similar layout supporting borderless windows, dragging the window using the top panel will result in the mouse moving to the center of the window instead of the title bar.

STEPS TO REPRODUCE
1. Start Plasma Wayland session.
2. Use Unity layout.
3. Drag maximized window by using top panel.

OBSERVED RESULT
The window is dragged by the titlebar.

EXPECTED RESULT
The window is dragged by the center of the window (like Meta+Drag).

KWin wayland has no interface to position mouse appropriately

So, for now, this will remain impossible. Should I close this?

This appears to work as described now based on triggering a move from the task bar
