[BUG 1.128] Changing screen resolution results in tiny window / oversized window / bad mouse mappings

What I was trying to do
Tweak settings after starting the game for the first time.

What happened
The game shrunk into a roughly quarter-sized window, even though full screen was on.

What I expected to happen
The resized window should have been full screen.

Additional information
My native screen resolution is 2560x1440, I was changing it to 1920x1080 because the text was too small on my laptop (even with DPI aware on).

I just tried flipping the DPI aware switch after reading the tooltip, but things went wrong in a different way (see image). The mouse also no longer “matches” what’s on screen, i.e. I have to move the mouse to the middle to hit a button at top of the screen.

Changing back to native resolution makes things go even more nuts:
