When upscaling a video with subtle tone shifts and dark shadows, blocky artifacts always appear. in a 720p video upscaled to 2160p, the blocks are 30*30 pixels.

Are you seeing the same issue with Rhea or just with Rhea XL?
Testing confirms it is only Rhea XL.
Can you share the logs for this as well, that way we can have the devs look further into this and we can run some tests to replicate with other videos as well. You can link them here or send to the support team directly if you do not want to post them publicly. help@topazlabs.com
To gather logs, please select Help > Logging > Get Logs for Support and attach the zip file to your reply.
