Comment 13 for bug 48226

I can confirm the issue stated here. I use a panel on the right side of the screen and it sometimes moves off to the left after the pointer leaves it "too fast" (definition needed here). It's easy to reproduce by setting "[un]hide delay" properties to 0 and then rotating your mouse against the edge of the screen where the panel is hidden, making it show up and go back in quick succession. Panel's "position" property remains unchanged though.
