Is "Allow Window To Be Resized" Fixed yet?

I’d like to use some oldie but goodie synths in Cubase 12.0.50 like the HG Fortune stuff, Nuklear, Hybrid 3, and other “too tiny for my bad eyes” synths. HiDPi is enabled as is CPU scaling in my video card software. When I activate “Allow Window To Be Resized”, it does nothing. Nada. Zip. There is no arrow to tug on a window’s corner to resize it. Nuklear did show arrows, but when I do resize, I get a black box instead.
