Plugin GUI unresponsive in Cubase 15 / Win 11 / VST3 64

[mbfranck]

When I open the Early Reflection plugin UI, th whole other Cubase UI stops updating. I cannot e.g. click on another channel while plugin is open. After trying to click into the arranger window, I may return to the plugin window, but now the plugin UI is unresponsive, too. In this case, I cannot close the plugin via "x", BUT I can close it via right click on taskbar.

Even with the plugin initially responding, it will never update any numerical values after turning the knobs until I also change the reflection type.

When I switch the plugin to generic standard steinberg controls instead of the custom UI, everything works fine, so I would recommend this as a workaround for anyone running into the same issues. You need to close and reopen the plugin window once to apply the switch to generic controls.

Can confirm this happens as well on W10, Reaper, CLAP format.
Early Reflections works properly but doesn't allow anything else on the screen to update, only itself.
Closing and re opening track effects sends you back to ER in any case.
All the other plugins work fine.

EDIT:
Plate doesn't update parameter values under the knobs until the plugin view is closed and re opened.

Have to add: Win11, Cubase 15 Pro. Any news on this one?
