Loading the CP wrapper for Addictive Drums (VST) in Studio One works fine.
But after moving the plug-in window it's not redrawn properly, resulting in a plain white window.
Same for Lounge Lizard 4 (VST).

Studio One 2.6, 32-bit

Yep.... it's one of the weird issues we're facing on Mac computers

The plug-in GUI stay at the same place while the window is moving behind, right? Could you post here a screen snapshot to be sure we're talking about the same thing?

It seems to be related to Carbon/Cocoa cross hosting, and to some plug-ins. This issue is not "standard", so very hard to fix. But we're working on it and continue searching a solution.

Here's a screenshot:

Green anybody?

This is the AU version of Addictive Drums:

It should be ok now.
