Plugin GUI unresponsive until closing and reopening window - shaperbox 3

[meutbal]

I'm using the audiogridder server through crossover to run the windows vst of shaperbox 3 on my macbook. the vst loads and works but the GUI is unresponsive when i first make any adjustment or try to click on anything inside the GUI.
I have to click somewhere or move a knob, then close the plugin and reopen it in hopes of seeing that I clicked on what I wanted or turned the knob in the right direction. That last part is almost verbatim how another user has described this issue back in '21 (#404), but it hasn't been resolved then, so I thought I'd give it another shot.
