- Start the drawing sample
- Press F6
- Scroll around and watch the stars wxSET, wxCLEAR and
wxINVERT. Move them out of the window and back into it.
=> You'll find ugly garbage.
- Now press Ctrl+G several times to shrink the display.
=> The three mentioned stars don't shrink but stay in
After shrinking the image, you can now also see
additional wrong pixels in e.g. the "original image".
Compare it with the "with colormask" image where those
ugly pixels do not appear. This is described in
Maybe, those two user-scale problems are somehow
related or caused by similar code?
Tested on Win2000.
