Nice!
Seems like the same thing is also still happening in ScrollAreas and when moving around Areas with ScrollAreas, but this is already a great improvement:

Only seems to happen at odd zoom factors though.

…7710) Sometimes when moving a window, having a tooltip attached to the mouse pointer, or scrolling a `ScrollArea`, you would see this disturbing effect:  This is caused by us rounding many visual elements (lines, rectangles, text, …) to physical pixels in order to keep them sharp. If the window/tooltip itself is not rounded to a physical pixel, then you can get this behavior. So from now on the position of all areas/windows/tooltips/popups/ScrollArea gets rounded to the closes pixel. * Unlocked by #7709
