Redrawing every image in my application in every call of on_draw takes
too much time, so I updated my code to work the following way:
Every time an image is modified, it is added to a queue. Every time
on_draw is called, it iterates through the queue and draws each image.
When the application loads, every image is added to the queue.
window.clear() is never called.
For some reason, the application keeps oscillating as I use it. After
one update to one image, half of the displayed images vanish. After
one more update to an image, all of the vanished images reappear, and
the other half of them vanish. After one more update, all of the
displayed images vanish, and the other half reappear again. I put
print statements in the method that draws images, and it is only
drawing one image every time I update an image. This implies to me
that there are perhaps multiple graphics windows being drawn to.
Any suggestions for where to look to fix this problem?
I would suggest you create sprites and use a batch to draw them all at once.
