To my surprise I'm finding that I really like Unity in 11.04, but there is one small problem with it which means I have to log in to Classic No-Effects a lot of the time.
When working in GIMP using a Wacom pen (which I do a lot), not all the lines I draw show up. Maybe every 1 in 5 lines, just don't show up, and it's like the brush outline freezes. This becomes pretty annoying when drawing, which is why I log in standard GNOME without effects when using GIMP.
There is a minor problem that I think may be related, and that is that sometimes when I open a windows in GIMP, such as the Save or Open dialog, I won't be able to click anything in it with my pen. I then need to click the canvas in the background, and after that everything works. It seems as though the brush is stuck on the canvas, which is similar to what happens when drawing.
I've tried different compiz settings with vSync and others, but nothing that made this work. This also seems to only be a problem when using a Wacom pen, and not when using the mouse.
Has anyone here found a solution to this problem?
