Resolution Note:

This is by-design because when "Allow HDR" in ON, an intermediate texture (HDR format) will be created and that means there will be a final blit from this texture back to the screen. when "Allow HDR" in OFF, the blit wouldn't happen as contents are directly rendered to the screen User can use Frame Debugger to compare these 2 situations. User can override this final blit by having this in the code. But just make sure the blit source texture has the content that the user wanted. void OnRenderImage(RenderTexture src, RenderTexture dst) { Graphics.Blit(src,dst); }
