The settings dialog is too high, it starts out of screen bounds

Describe the bug/issue

Using a 4K/UHD monitor at 288 DPI (300 % zoom) the settings dialog always starts out of working area bounds because the dialog height is slightly too high.

Thanks. Most projects I think do not close issues before a beta version is online. A Fixed/Done label/tag can be used meanwhile.
