Blur nodes not working, looking like a pixellated mess

I’ve been trying to add a gaussian blur effect to my animations and it just turns my work into actual pixellated garbage. I recently upgraded to Harmony 16 so I thought that might be the problem but then I tried the exact same thing in Harmony 15 and same thing happened only the pixels were blue instead, for some reason. Also as a note i’m using Harmony Premium. I’ve attached pictures as examples along with the layer properties window, showing that the effect has been added but not modified, yet the mere presence of this node seem to just break everything.

I’ve been trying to find any solution to this but nothing is coming up
