URP Postprocessing & TextMesh Pro

Hi, I am using similar approach to render my UI Components as @EyeMD:

But I am not able to get rid of these pixelated edges on my FontMesh Pro texts:

Here is my camera setup:

I have no idea what´s wrong, but I know these pixels are there becouse of postprocessing…
The Main Camera has postprocessing turned on and the UI Camera turned off, but it seems just does´nt help.

Please, someone help

Changing the anti-aliasing function to None or SMAA on the Main Camera fixed the issue.
