Upon first opening the GUI after a reboot, relog, or switching user, the GUI is put into the top left corner of the screen. Resizing/repositioning is largely irrelevant since upon a reboot, relog or user switch it goes back to top left corner again. Legacy Windows system apps do this, it’s quite irksome.
All previous versions didn’t do this; they remembered user positioning and sizing of the GUI. It would be nice to have this back.
