When running the Dashboard example I can get it to run on my main display, but not my secondary display. The weird part is that if I change the Windows display settings to switch which display is the main one it will swap which one it works on, so it's not display based itself. I've recorded two videos, one on the current main display (external monitor), and one on the secondary (laptop monitor).

Secondary laptop: https://www.loom.com/share/3086aa17bb33407ba0abb11a7ac08dab

This seems to happen with any Qt example that I can get to open on the non-main display. It seems to potentially be hardware specific because other laptops I have access to do not display this behavior.
