CAD somehow randomly resets my GUI size back to "normal" and doesn't let me change it back until i put CAD in a chest. And it doesn't render PSI bar either unless it's "normal". My window size is 1280x1024. It really sounds like some weird corner-case.

Can't reproduce. Try deleting your config.

Perhaps it's better to just do the ScaledResolution calculations yourself, or have a class which extends it?

Your window size is not 1280x1024, it's smaller because of the windows bars. Can you go to the snooper settings and tell me how large it is there?

There isn't anything about it in snooper settings, debug shows it's 1280x975.

That works as well.

Nope.

Psi bar is still invisible, though.
