A crash occurs when attempting to run the Pixel Inspector tool after entering 'r.GbufferFormat 3'
What this does is defines the memory layout used for the GBuffer.
(affects performance, mostly through bandwidth, quality of normals and material attributes).
0: lower precision (8bit per component, for profiling)
1: low precision (default)
3: high precision normals encoding
5: high precision
Crash occurs:
4.15.3 - 3450819
4.16.1 - 3466753
1. Create new blank project.
2. Bring up Console Command and enter 'r.GbufferFormat 3'
3. Go to Developer Tools > Pixel Inspector and start inspection.
Outcome A crash occurs as soon as you press the magnifying glass to initialize the pixel inspector.
Expected The pixel inspector tool runs without a crash.
