Layers glitch on some frames when adding blur, glow or other effects.

Hi everyone, I'm having a problem with AE2019

Whenever I add an effect like glow or blur the effect makes the layer glitch out on some frames. I've looked for solutions but can't seem to find anyone who has the same problem.

First thing I would try is delete cache & update GPU drivers. 

What kind of layer is it? System specs?
