Unpatched, it stayed at 2592x1944 in all 32 and the 1296x972 streams gave no frames. - With each stream started from runtime suspend, the path v2 changed, OUTPUT_SIZE matched the requested size in 12 of 12 streams (as it did unpatched), all with complete image data. The test scripts, the analysis of their output and this summary were prepared with an AI coding assistant (Claude); I ran the tests on my Surface Pro 9. Tested-by: Chris Simpson
