Comment 1 Henning 2024-06-08 23:36:23 UTC
so the main window gets overlaid with a dark layer it seems, for a short time, which then disappears. This may be because the "moving the expanding dark size preview back thing" is shown above the window and not below.

Not sure if this is the right component btw.

Not sure how this could be a regression. What you're seeing is pretty much the intended behavior, it's just that it looks a bit odd because the overlay square is dark.
