SUMMARY If a GTK window (happens with FireFox or Gnome Web) started maximised mode, and I drag down the title bar to make the window unmaximised, release the mouse,and then try to resize the window at the top-left/top-right corners, it seems that the window's x,y positions get inverted. STEPS TO REPRODUCE 1. Start Firefox or Gnome Web. Maximise its window, then close it. 2. Start the app again. The app starts with the window maximised. 3. Click the title bar (the thick empty area on the top of the window) and drag it down until it becomes an unmaximised window. Release the mouse button. 4. Try to resize the window on the top-left/top-right corners. OBSERVED RESULT Window jumps to up/left side. EXPECTED RESULT Window stays where it is and the size gets resized.

Created attachment 168823 [details] screen recording I thought it was GTK window thing, but it happens with QT6 apps, too, like KWrite. See the screen recording.
