high DPI reverts after tens of hours of runtime

[rakslice]

I normally run orion retro in Windows with QT high dpi mode enabled through the environment:

set QT_AUTO_SCREEN_SCALE_FACTOR=1

This results in larger UI elements and chat text to suit the 4k 30" monitor I usually have it on.
But if If I leave Orion running overnight and come back to it, it has reverted to very small text.

There are a lot of dynamic bindings connecting the high DPI mode; there may be some kind of pathological convergence behaviour at play. Or else, some kind of event that happens on an idle machine (screen blanking? session locking? something else that I haven't thought of being automatically reset?) clobbers the setting.
