Here is a copy of my rectangular example. If you wanted rounded patterns (between the window and the desktop background, use UpdateLayeredWindow (for Windows only, but I think this function has an equivalent on Linux).
Example #1 with rectangles :
Code: Select all
Define tempWin = OpenWindow(#PB_Any, ExamineDesktops(), 0, 0, 0, "", #PB_Window_Maximize | #PB_Window_BorderLess | #PB_Window_Invisible)
If DesktopWidth(0) <> WindowWidth(tempWin) * DesktopResolutionX()
    If #PB_Compiler_OS = #PB_OS_Windows And OSVersion() > 70
        MessageRequester("Don't forget to...", "switch the user option ! (menu Compiler)")
        End
    EndIf
    MessageRequester("Please switch...", "the dpi option on ! (menu Compiler)")
    End
EndIf
