When Krita is maximized, dragging the title bar in order to move the window to another screen will automatically resize Krita to close to 10,000 pixels wide, spanning across all 4 of my screens. It's nearly impossible, if not a huge hassle, to resize Krita back down to a reasonable size. This seems to happen on all releases. Some specific details about my setup in case it's non-reproducible elsewhere: Display 1: Cintiq 24 Pro, 3840x2160, 225% scaling Display 2: generic monitor, 2560x1440, 100% scaling [Main display] Display 3: generic monitor, 2560x1440, 100% scaling Display 4: generic monitor, 2560x1440, 100% scaling The issue happens if krita is dragged out of fullscreen from any monitor, most of the time. Sometimes it doesn't. Sometimes it gets really thin and really long. Sometimes it only happens when dragging between different scaling percentages.
Does it not happen for other programs? (I guess not, but I'm asking since I would guess a dragging from a fullscreen is not something one do with every program). Especially Qt-based ones like Kdenlive?
I'm marking this as confirmed because I know that this can happen due to QMainWindow::saveState and restoreState not handling devicePixelRatio correctly. Fixing this would probably require hacking into Qt's code though.
Or rather, it should be QWidget::saveGeometry and QWidget::restoreGeometry

I've seen it happen with one or two other programs over the years, but they seem to be issues with those specific programs and not with the OS' handling of windows in general as other applications are fine.
