    Description

      [Windows 8.1]: After maximizing a window and toggling the frameless window hint and moving to another monitor then the window can be too big. To reproduce this the windowflags example can be used. It needs a multiple monitor setup and for the task bar to appear on both monitors too.

      • Maximize the preview window on your primary screen
      • Check "Frameless window" to remove the frame of the window. Note that the taskbar is still visible.
      • Now uncheck the "Frameless window" and maximize the preview window on your second screen
      • Check "Frameless window" again to remove the frame of the window. The window now overlaps the taskbar on the second screen.

      This is not a problem on Windows 7 because there is no way (at least I was unable to find one) to have the taskbar across both monitors.
