Confirmed by another user, if you open a Cherry Audio Synth (VST3 synth) in KK within Ableton you get this display:
All synths are like this, happens even if you manually load the plugin from the plugins menu and only happens loading the VST3 version of a CA plugin in the VST3 version of KK within Ableton.
In standalone KK, displays fine.
Loading a VST3 version of CA plugin in Ableton displays fine
Loading VST2 version in KK displays fine
Loading VST3 version in KK VST2/3 is broken
Instrument still functions, just no GUI
No idea if this is a Cherry Audio issue or a KK issue but only this combination is at fault. Will have to raise tickets with NI and CA for this one
