Can reproduce. Now the target seems calculated based on the center of the windows, which can be different from the location of the cursor.

By the way are you using some 3rd party layout script for the window positions in grid view? The current layout algorithm shouldn't produce a layout like that.

Nope, it's layout method "Natural". "Smart" is first introduced in 6.1
