I've been working with Painter X.1 a couple of months now and I've been bugged about one thing all this time... At times some graphical bugs occur. If I for example open another window over Painter that window can later some times get stuck in Painter. I then have to drag the canvas out of frame until the bug no longer is visable.

Another thing that annoys me is that whenever I move the canvas around the images sort of breaks. It doesn't break like it gets ruined or anthing, but it looks lika graphical issue over all.

These issues have I never encountered with Photoshop so I wonder if this is a common thing or if it might be my graphics card.
