I'm having more problems with JUCE plugins in Polac, specifically BBC Orchestra (Spitfire) and LABS. I just bought a new laptop on Windows 11, 16 GB, i7, SSD etc.
I have experienced problems with JUCE plugins before, e.g. Valhalla Supermassive but I have been able to solve these with either
a) unchecking 'embedded VST gui' (via right click > preferences in Polac etc)
b) unchecking through Bridge mode (CTRL ALT on GUI)
c)switching off 'run in a separate process' or
d) some weird process of trial and error with checking and unchecking different boxes in the preferences tab and restarting to see if it works

I had BBC Orchestra working perfectly but LABS wasn't .... I filled around in the 'per plugin' preferences etc for LABS (without tinkering again with BBC)....
Now LABS works perfectly and I cannot for the life of me get the BBC plugin to work.
In this case it isn't the flickering menu problem...it's that I cannot even see any GUI, just a small white box with a title.
I actually don't mind if I can't close the GUI completely... I would just like a useable GUI.
It's weird because it was working perfectly.

Any thoughts...
