Looking for an Effect of a CRT television

Hi there!

I'm looking for an effect of a CRT television, something like the following effect. Main point is that it should be a shader on a mask object and not a layer/layout effect. Would be lovely if somebody can share such.

I was trying to port the linked effect to construct 3 , still resulted in instable work and visual artifacts regardless of project settings and browser. I can share adapted files if somebody can try to help with it.

Video from an original effect author

did you try these two already?

Thank you! That is what i was looking for, for some reason i was not able to google them.
