I have found this thread about something similar. I will try this.

> I am also experienced VST3 resizing weirdness in Reaper (64bit, OS X). In my case I have observed that if either setResizable or setResizeLimits is present in the editor’s constructor, then the width and height defined in setSize are ignored, and the plugin GUI is initially scaled to fill Reaper’s FX window. Additionally, if setFixedAspectRatio is also present then resizing Reaper’s FX window by dragging its edges will cause the plugin GUI to be resized, which is not the case with VST2 plugins…
