Move off-screen SUB-window back to visible screen on Windows 10

Question

This is NOT a duplicate to the common question, how to get an application window from an offscreen position. I am familiar with those problems and know the solutions, like moving windows with SHIFT+WIN+ARROW keys, WIN+SPACE and Maximize, etc. However in my case I have a windows Qt-based application that has a child window that appears in some cases and this child window remembers it's position on 3rd monitor I don't have at home. No common tricks work to resolve this, since they cannot be applied to the child window; if they work at all, they get applied to the main window.

I could only find one similar case with Firefox sub-window and it had a solution specific for Firefox.

Any hints, please?

Answer 1

Hey in case anyone else stumbles to this thread, I was facing a similar problem with Tableau where a child window is needed for exporting to PowerPoint and it kept opening off screen. A one-time fix for the problem was just to open settings, navigate to display and change the scale ( I changed it from 100 to 175 ) and this somehow arranged it so that I could drag the window to middle of my screen and then change back the scale to normal.

As said, no trick worked. Even changing setup between mulitple screen modes.

However, I found that for this very reason the system has a reset button located at Preferences --> User Interface: Layout, which one has to trigger and restart the NX system. This is obviously not a general solution for qt sub-windows on Windows, let alone all the sub-windows on Win10. But at least it helped in my case.
