#1476 On a hi-DPI monitor, any newly created windows will appear behind the main window
This has been tested with 11.1.0. If, for example, you click "Text Search" under the Tools bar, the dialog window will appear behind the main window. I have to do Shift-Win-Right in order to see it and make use of it.
I think this might be fixed in nightly 1906.
