Custom control repositioning incorrect on some systems

[fafalone]

While I use 150% scaling myself, others using it report custom controls are repositioned incorrectly. I'm investigating this, but as I can't reproduce it right now it will be challenging.

Fixed as of v1.2.3

Caused by minmax effects being disabled in system settings; this changed the size of the window when it was still expected to be the old value, making the code think it hadn't been resized.

Thanks to Wayne Phillips for figuring out what setting caused the issue.
