Description Tomaz Vajngerl 2016-04-29 14:09:10 UTC
When dragging the scrollbar the thumb is not updated immediately on Windows, which makes scrolling feel more sluggish as it really is. The content updates quicker than the scrollbar thumb itself.

This happens with and without OpenGL but with OpenGL enabled it is much more notable.
