Unresponsive Scaler 2.5.0 on Apple M1

I have come back to use Scaler after some time (2.5.0, both VST and VST3, running in Bitwig Studio 4.1.2 on macOS 12.0.1 on Apple M1 Pro) and I am finding the UI very unresponsive. Watch this video to give yourself an idea: what you see is real-time, without any post-processing but for highlighting the mouse clicks.

It is not normal that it is so slow, right? Is it a known issue or it is just me? Thanks.

2.5 working fine here on Bitwig 4.1.2 but on Windows. Have you tried changing the Bitwig Plugin Hosting options this sometimes works for me when Plugins misbehave.

@tactile_coast thanks for the suggestion, yes I’ve tried that, and I have also tried the VST 2 version, the behavior is the same. My best hypothesis at the moment is that the VST is not yet compiled natively for Apple silicon, and for some reason that affects especially the UI.

Can confirm this issue, Scaler 2.5.0 on Bitwig 4.1.2 feels very sluggish on my M1 Macbook Air.
