-RM-306-MR-WGEOffscreen Camera uses a different depth-range during rendering, causing strange clipping artefacts when blending offscreen and onscreen paths.
The offscreen rendering camera uses a different near and far plane compared to the original onscreen camera. This leads to weird clipping artifacts when combining an offscreen and onscreen pass.
