RootPane: undone commits 7b248427f0 and c6d1ed91a7 because it seems to have no effect anymore

Browse Source 
- on Windows with FlatLaf window decorations, maybe because of 7f02eb9cf0
- on Windows with standard window decorations, it seems not to work (still shows "white lines" @2.25x on Windows 10; Java 17)
- macOS and Linux do not support fractional scaling and "white lines" shown never be shown on that platforms
