Certain VST3 plugin GUI jumps a size every time opened

I have certain VST3 plugins that every time you open the GUI their GUI jumps up a size after about half a second. its cumulative so it just goes up and up in size the more you close/open it. kirchhoff EQ and savant quantum evolution are the 2 that I’ve noticed most recently tho there are probably others.

anyone know what’s up with this? is there a setting somewhere I could change? at the moment I have to grab the corner and resize these 2 plaugins every time I open them which is a workflow pain.
