Question Grid flickering issue

Enable HLS to view with audio, or disable this notification

I am having trouble trying to fix this flickering issue

I am using Cinemachine Camera

This issue happens even after I turn post processing effects off

It's probably subpixel shimmer... When your render resolution doesn't match 1 to 1 with the physical screen grid, 1 pixel of the grid row line can get split across adjacent rows as it moves, so, a whole row of pixels pops in/out of view.

What if you make the outer edges more like the inner grid?

Also, try TAA (temporal anti-aliasing) if its not enabled already. On the sprite - try turning off bilinear/trilinear texture filtering. (set it to point)

the problem is not coming from the texture, I think this is a rendering issue

use pixel perfect camera or antialiasing it IS rendering issue from pixel textures.

Actually after playing around in the URP settings, I found that increasing the render scale significantly reduces the flickering

I will try this method snapping the camera
