System information
------------------

The attached demonstrator shows following bug on my Mint 20.1 Cinnamon:

When starting the app in the IDE, in most of the cases (not always) the clock-image is displayed at the left side of the screen, although the FMain (invisible) has been positioned at the right side of the screen. You can reconfirm the position of the invisible FMain by moving the mouse cursor to the right side of the screen and observe the changes of the cursor shape.

You may have to start the app several times to see the bug. I friend tried the demonstrator and confirmed the bug on his Mint 20.1 Cinnamon machine. 

The bug does not occur, when the FMain.border - property is set to True. What about the y-position of the FMain? It seems to be offset by the FMain title bar, which should actually not be there and not be considered, because of the switched off border property, or?
