Created attachment 108748 [details] Overview misalignment If I try to enlarge the overview past a "certain size" the overview keeps extending but the image stops expanding with it and the red rectangle becomes misaligned. the "certain size" is roughly half my second monitor's size with a 1920x1080 image (which happens to be my monitor resolution) and maybe 1/4 of it with a 1080x720 picture. reducing the size of the overview until it matches the scaled image size causes the rectangle to align. It's also worth noting that I have 2 monitors, though I suspect the issue will be reproducible on a single monitor system. Ideally, the image would continue to expand to fill the overview and the red rectangle would have proper alignment.
Um... I haven't tried to reproduce this, but I do have to wonder _why_ you're abusing the poor little overview docker like this. If you want to have a screensized second version of your image, why not use a second view in a second window of your image?

Also, opening a second window opens a second set of toolboxes (workable by setting your second window to a different workspace, devoid of tools) and doesn't switch the view whenever you switch which image your editing (overview does, however it's workable by changing it yourself). regardless of the -very- tedious possibility of using a second window with a second view to have reduced functionality this issue also affects what you might consider "reasonable" sized overview boxes when viewing very small images.

Okay, I've managed to reproduce the issue. Not fix it, though...
