High when I test my finished VST3 plug-in in Cubase I’m getting a 2 second pause when I first click a control, then afterwards it seems to run smoothly. I can’t use VST3 because of this.
I’m using OpenGL which renders 2 quads. They do use a simple shader that renders a frequency map and a loudness graphic, both set to setContinuousRepainting.
This is only a Cubase problem, but I’m surprised it hasn’t been spotted before.
I suspect it might be something to do with Cubase wanting to repaint quite quickly compared to other hosts.
edit running the same build as VST2 is fine in the same host (Cubase LE Elements 9).
I’m using a brand new iMac with Mojave, and 5.4.1 of Juce.
Anybody have any ideas?
