FXAA makes strange flickering on far distance objects


 I have some issue that bothers me for long time now.

I have a mesh model moving in from far distance.
I have to use FXAA - because it’s seems to work the best in my case, comparing to TAA which creates even more artifacts on moving, overlapping objects.

I have tried all different setups and tweaking of materials. It gives always same effect visible in gif:


What else I can look for to minimalize this blinking effect :confused: ?
Thank You and stay creative.
