Issues with a VST plug-in under Linux in Renoise

I'm developing a VST plug-in on Linux using JUCE 3.0.3 and I'm testing it on Renoise. Sometimes when I try to open the GUI it freezes as shown in the picture and Renoise complains that: "Renoise LOG> VstWindow: Plug neglected effEditGetRect..." or at least I think that is where the issue lies. Can someone shed some light for me here? I'm sorry if I neglected to provide some obvious additional info.
