Description

Buffer visualizations rendered in HDR through the high res screenshot tool or sequencer using DX12 and r.postprocessingcolorformat 1 will result in renders that only capture the first row of pixels. 

Steps to Reproduce
  1. Launch with the command line -dx12
  2. Run the console command r.postprocessingcolorformat 1
  3. Open the high resolution screenshot tool and check the boxes for buffer visualization targets and HDR format
  4. Take the screenshots

RESULT

The base screenshot renders correctly, but all buffer visualizations are just the first row of pixels repeated.

 

EXPECTED
The buffer visualizations should match their in-editor appearance. Using the high res screenshot tool without r.postprocessingcolorformat 1 will give the correct results as well. 

NOTE
This effects sequences rendered with custom render passes in HDR as well.
