Description

Hi, I think there's something strange going on with:

  • imshow()
  • animation_frame
  • binary_string

From my tests, binary string (BS) causes the animation to glitch out and freeze, sometimes making the slider pop out of place, and the only way to "reset" the bug is to double click the image to auto resize it.

attached: two videos denoting the problem, it's a simple px.imshow(image, animation_frame = 0, binary_string = True)

TLDR - BS images load faster, but "freezes", no freezes when BS = False

Research direction

Start with the minimal px.imshow(image, animation_frame=0, binary_string=True) reproduction and compare it with binary_string=False. Investigate the animation and slider behavior shown in the attached videos; done means binary-string images animate without freezing or displacing the slider, without requiring a double-click to reset the view.
