White line on top of Windows app´s
Some windows app´s like settings, calculator, almost all windows store apps have a white line on top of the window, is there any way to fix this? i am managing the windows with this config: Config_rule=ApplicationFrameWindow;.*;;1;0;0;0;0;0;

full screen shot that is better representative of the issue:

Sorry, I could not reproduce the issue with bug.n 9.0.2 on Window 10 1903 (Build 18362.418) and te following Config.ini lines:
Config_showTaskBar=1
Config_layoutGapWidth=5
Config_rule=ApplicationFrameWindow;.*;;1;0;0;0;0;0;
Although, I did recognize white bars on top of the windows in the Alt+Tab-Menu, if I leave Config_layoutGapWidth out.
Which versions are you using? Can you reproduce the issue with only Config_rule=ApplicationFrameWindow;.*;;1;0;0;0;0;0; in Config.ini?
