RenderTexture OnGUI Offset

Question

Hello, I'm working on camera transitions that involve drawing a RenderTexture OnGUI. The RenderTexture size is set to the Screen's width and height and is displayed using DrawTexture at coordinates (0, 0). Despite t$$anonymous$$s, it seems that the RenderTexture is always offset by a small amount when compared to its camera.

Transitioning from a camera to its RenderTexture is not very smooth. You can see a small pop as the RenderTexture seems to be offset compared to its camera. Why is t$$anonymous$$s the case? What are some possible solutions to t$$anonymous$$s problem?

Edit: It seems that a RenderTexture's contents are always offset by 1 pixel upwards when compared to its camera. We're missing a whole row of pixels on the top. How can we tackle t$$anonymous$$s issue?

Currently, I'm drawing with GUI.DrawTextureWithTexCoords and using the texcoord rectangle to offset by one vertical texel. T$$anonymous$$s gives me a duplicated top row due to texture clamping, but at least the rest of the texture matches my camera.

Did you submit t$$anonymous$$s as a bug?

I haven't submitted a bug report for this issue, but that's a decent workaround.
