Getting the same thing with Melda VST3 plugs. Win 7 64 bit, Melda version 10.01, Reaper 5.24. I don't get the interface going white as the fellow above mentions, only the resizing, and only with the VST3 versions, not VST2. I also noticed that just clicking once in the Melda interface resize areas around the edge brings it back to the size it was before closing (whereas normally you'd need to click-drag the edge around). Hope the GIF shows clearly what's going on. Thanks, devs.
