OSX: If a vst gui is open, Renoise gui becomes almost unusable

Hi,

if a plugin gui is opened, the framerate of Renoise’s GUI drops so low, that it becomes almost unusable in some cases.

Really would like to help here, but please give us a little bit more info.

With which VST (bridged or not) in which song (if it matters) on which computer (32 or 64 bit Renoise, which version of OSX).
Does it behave the same in other hosts, in Renoise 2.8, and so on?

yeah, give us some details on this. are ur plugins bridged or not, etc…
