When I restore an A/B preset on certain plugins, I get a glitchy display on the track DSP UI. Showing then hiding the parameter sliders fixes it. I’m using Renoise 3.4.1 on macOS Catalina.
Steps to reproduce look like this:
Load CHOWTapeModel VST3 (a free plugin, as an example. I have noted the same problem with other VST3s and AUs)
I notice the thread title has been edited to say VST3 plugins, but I’m actually getting a similar issue with the AU version of CHOWTapeModel. It seems to happen with any plugin that uses boolean buttons or dropdowns on the native UI.
