Helm VST on macOS Sierra: GUI won't update


the GUI of the freeware Helm VSTi doesn’t work properly anymore in Renoise 3.1.1 64bit, I guess since macOS Sierra. The Gui won’t update anymore, it only shows the initial graphics drawing.

It works just normal in any other DAW though.

Is there any way or workaround how I could make this version work again? Any ideas?

Here is the version: Helm 0.85 64bit macos


P.S. I’ve seen similar problems in other VSTis, too.
