[Bug Report]

It seems that OBS 26.1.1 has a bug involving text/app scaling and the VST 2.x plugin.

In Windows 10, when running OBS on a high res monitor with text/app scaling turned on, everything in OBS seems to scale properly, but when a VST 2.x plugin filter is applied to an audio source and you open the plug-in interface for it in OBS, The plugin displays correctly, but the window/window border scales again to the set scaling size - ie: on a 3840x2160 display with 200% font/window scaling enabled (the equivalent of how things would look if you set the same display to 1920x1080) the selected plug-in interface loads and scales to the correct size, but then makes the window/border and ADDITIONAL 200% bigger, resulting in a plugin that displays at the upper left 25% of the window, and 75% of the window is empty white space that can't be resized/removed.

Or, it's scaling the window, but *not* scaling the plug-in interface into it, depending on how you want to look at it. Possibly the latter since I just noticed it's a little less readable.

Either way, I've attached screenshots to show what I'm talking about.

Pic [1]: - Regular setup, 3840x2160 (4k) monitor, Windows text/app scaling @ 200%.
Pic [2]: - Same display at 4k, but set scaling to 100%
Pic [3]: - Same 4k display but set to 1920x1080 (1080p) resolution @ 100% scaling.

I'm having the exact same problem with a 4k monitor and ReaEq and other VST 2.x plugins on OBS 27.1.1.
