Very rapid flickering with certain gesture combinations

[Alex-Michie]

I have a square crop view, and an image that is taller than it is wide, and when I zoom out all the way I can see black bars at the edges, which is fine.

However when I remove one of my fingers and then slide the remaining finger touching the screen to the left (sliding towards the right seems to just align the image to the left) the image will rapidly alternate between being aligned to the right of the screen and being aligned to the left.

It appears to alternate between those 2 states as rapidly as possible as long as I'm sliding my finger leftwards.
