Description arcinthesky 2024-02-09 23:24:13 UTC 
STEPS TO REPRODUCE
1. Trigger the keyboard shortcut to move a Window (for example, Dolphin or Firefox)
2. Move Window to any other spot on the desktop, and left click the mouse.
3. Now the window is in a new spot, move the mouse around and you will see it is pointing at things that are not under the cursor.

OBSERVED RESULT
Mouse cursor does not match the physical location within the window. In order to get your mouse back to be pointing at the correct spot of the Window, you have to move the cursor out of the window, and then move the mouse back into the window.

EXPECTED RESULT
Mouse cursor should be interacting with elements that are directly under the mouse cursor within the window.

Comment 1 fanzhuyifan 2024-02-10 00:54:52 UTC 
Can reproduce on arch, source build from master, wayland. 

Note: this happens when the initial window isn't maximized.
Comment 2 fanzhuyifan 2024-02-19 01:33:54 UTC 
The problem seems to be the surface getting a wl_pointer.enter event when the move starts. This does not happen when the window is moved by holding down meta and dragging.
