UE 5. The noise glitches and blinks on hair texture in viewport

Hello everyone!
I have a strange problem with displaying of the hair’s texture in viewport. There is some noise glitches, the texture blinks in many local places regardless of the material. In the video the hairstyle have two different materials and the problem is present on both.

I tried to turn off cast shadows, changed the number of samples in the light source, but nothing helps.
I am a beginner in the Unreal Engine (the version is 5.4.4) and I have this problem on two computers: on Windows 11 with NVIDIA Geforce GTX 1660 Ti and on Windows 11 NVIDIA Geforce RTX 3060.

Maybe the problem is somewhere in the settings, but I don’t understand where exactly.
I attach the link on my google disk with video from UE viewport below. This problem don’t seem on photo, need a video.
I hope someone will help me figure it out, thanks!
