Short description of error
When rendering out the junkyard scene at 2x resolution, 500 samples and the Open Image denoiser in the compositor and adaptive sampling on when the gpu takes over tiles unfinished by the cpu artifacts are generated when complete.

Exact steps for others to reproduce the error

download junkyard scene
set samples to 500
untick the denoise option (Optional)
enable Optix/Cuda on both cpu and gpu
enable denoising information in the render layers (didnt test if optional)
add the denoise node in compositing and connect it to the node group in place of colour (Optional)
render out and look at cpu tiles taken over by gpu when complete
