Would it be possible to adjust the behavior of isadora in a future update so that pixels on a display that are outside the boundaries of a stage do not pick up any pixel data from the edges of any stages that touch them?
Yes, I can log it as a feature request. It's certainly an interesting use case. I must say that I do find the stretched pixels kind of pretty though, and even know of Isadora users who also like this look and cause it to happen intentionally.
