Stripe Material Strange Wobbly Effect when repeat is high

I have encountered a strange wobbly effect when I used stripe material with repeat (around 100.0).

Here is the effect:

It can happen when the camera looks to the entity horizontally.

Do you know why this effect occurs? What can I do to fix this? I need to have a material that has bunch of stripes (lower repeat values may not be enough for my use case). Are there any alternatives for stripe material?

Thank you so much
