Thumbnails are wrongly generated

In Task Manager, if you move the mouse pointer fast to the adjacent entry then return to current entry, the activation of adjacent is slow which causes the thumbnail of the adjacent entry to be generated when the mouse pointer is currently positioned on current entry. This happens both on X11 and Wayland. See attached video for more info.

Can sometimes reproduce if I get the timing just right.
