Bulia or anyone else,

When I scroll use the vertical scrollbar everything is very smooth and the canvas is not smeared, but when I use my scrollbar mouse, the canvas is smeared in the update. This is especially true when looking at the tutorial. Can someone else verify this. Although this is not a bug, it is kinda weird updating of the canvas. Anyway...it becomes cumbersome to use the scroll mouse to move around with these weird updates, as you can't see exactly where you are heading. It would be nice if a similar update method was used as is with the vertical scrollbar wheel. NOTE: I have not looked at the code for thi.
