[Bug] The relative pan and zoom is not preserved (locked) when turning synchronisation back on

[NEKolev]

Is there an existing issue for this?

Current behavior

When I turn off the synchronisation between the images to adjust one of the images and then turn the synchronisation back on, the images return to their original state. In my opinion, the expected behaviour is for the images to “lock” as I have aligned them.

Anything else?

When zoomed in, red pixels from the mouse cursor can be seen, which do not clear after the mouse cursor is no longer in that place. It can be seen at the end of the clip, I don’t know if this is normal behaviour.
