VST-interface: Graphical update not working in Fabfilter Pro Q4

When using the Fabfilter EQ Pro Q4, the graphical live-update does not work at all.

Also in the Reverb Pro R2, the graphical live-update does not work

This should be fixed.

… it works in iZotope RX 11

Timeshaper also works in iZotope RX 11

Spectral Layers should do it, too!
