[SOLVED] Sluggish GUI on VST3 Mac

I recently did a big upgrade to my GUI, which involves lots of new assets and a bigger GUI overall.
The GUI approach is drawing bitmaps for every component.

I noticed after the update the VST3 build on Mac feels super-sluggish. Every buttonpress takes around 50ms or so to register, which makes it feel weird. The VST2, AU and standalone counterparts seem to work fine.

The builds on both Linux and Windows react lightning-fast.

What could be the root of the problem here?

Have you profiled the VST and VST3 versions and compared the results? That might help finding the culprit

I set

void	Component::setBufferedToImage (bool shouldBeBuffered)

to be true on the main editor, which seems to help in this situation!
