I’m finding the detection of whether a pop-up is too long to fit on the screen is not working on Windows High-DPI mode. Usually if it is too long then the pop-up appears higher up so everything fits, but this isn’t happening and it just falls off the bottom of the screen without scrolling or making columns.
– Edit: Suggested a fix here: Breaking Change: PopupMenus now scale according to the AffineTransform and scaling factor of their target components
