RenderTextureFormat.R8

Hey.

Is there something special about this format?

I get very weird values if I try to read from it's first 20% in horizontal direction. Everything else works just as expected and I only encounter this while using the R8 format.

For example:

1. Create a random read/write RenderTexture with any dimensions and set it's format as R8

2. Render it half-gray(or red if like to think in that way) pixel by pixel in a compute shader

3. Read pixel x=width, y=any and you get what you set it to

4. Read pixel x=0, y=any and you get undefined behavior
