This might not be a bug per se, but it sure is annoying! I have a three monitor setup, two of which are landscape 1600x900 and the third is in portrait orientation 900x1600.
The main Studio window cannot fit on the 900x1600 monitor at normal (100%) scale. It cuts off after the minimize button as the window physically cannot be made smaller to accommodate.
Floating windows do not appear to have this limitation (nor does Ui Explorer).
Is it possible to move this topic over to an Idea? I work with three screens, and it would definitely be nice to utilize my portrait monitor for those long sequences!
