I have a problem in series 60 with their screen.
I am using two Canvases in the program I am pausing one's repaint thread and display other. Two Canvas have threads that repaints the screen in current times. Let's say Canvas 1 and Canvas 2.

First I am pausing Canvas one's thread and resuming canvas 2's thread than I am displaying Canvas 2 but for 2 second I can see Canvas two's old screen than it resfreshes itself and I can see new screen. Than some times after I am pausing canvas 2 and resuming canvas 1's thread. When I display the canvas 1 again I can see it's old screen for 1 or 2 seconds too.

It is a biiiig problem for me. Helppp!
