Hello,
I have a bitmap in a main GeDialog group. When I click on either the child of another group within the main group or the bitmap itself, the bitmap redraws several times vertically incorrectly. It can be reset by resizing the window. You can see a quick screencast of the faulty behavior here. Can someone please help me fix this? Thank you very much!
Here is the random image, "random_img.jpg", that I used: 
This script looks for it on the Desktop.

fn = c4d.storage.GeGetC4DPath(c4d.C4D_PATH_DESKTOP)
image = "random_img.jpg"
path = os.path.join(fn,image)
self.bmp = c4d.bitmaps.BaseBitmap()
