I mean the subwindows of the GUI like editor, file browser etc.

By floating widgets, do you mean toolbars inside Octave IDE? I haven't moved any of those to float, if that's what you mean.

Does this always happen or only when you have floating widgets. Could you please test if you get a crash when all widgets were docked on the 4K Screen?

I dock my Windows 10 latptop to a 4K monitor. Octave runs fine. When I undock, Octave sometimes gets in a state where octave-gui.exe crashes every time on startup. I noticed the window opens briefly before it starts, where half the window is off the screen. If I dock again I can re-open it successfully.

In the distant past I used to commonly see problems with Windows programs that opened partially or entirely off screen. I wonder if that is part of the issue here. My laptop has much lower resolution and screen space than my external monitor, and if my Octave window was over to the side or down too far, or too large, it might be launching on the smaller screen size is causing a problem.
