3D Font renders instable

Hi,
I have a problem with a distant field font. It has an emissive glow material and is set in scene as a Text Render Component.

As you can see in the video, the font displays nicely when playing in editor. Here it looks sharp and crisp. Then in the build you can see that the font looks kinda “shaky” and “flickering”. On top of that when the screen resolution is set to a lower size, the font renders almost unreadable.

I am using Lumen Global Illumination and TAA.

While the material is set up like so:

I am using UE 5.3
I know this is a tough one. Any help would be awesome.
Cheers

anyone? noone? :see_no_evil:
