Slightly offtopic, but is there any open source/fair-code equivalent of Parsec that doesn't fail blatantly on non-standard aspect ratios such as 32:9 or have lots of other failure modes that they seemed entirely uninterested in fixing (marked as known issues for years, and no public source code available so I can't diagnose or fix them myself)?

I looked and there didn't seem to be much at all that didn't rely on just one vendor's as-buggy encoding stack - such as NVIDIA Experience software instead of just their drivers, and it's sad to see the closest tech to this this be part of some acquisition instead now by a company that seems uninterested in open sourcing anything even if it doesn't endanger any of their commercial market (e.g. Unity and their Burst LLVM compiler thing)... I don't even need all the matchmaking and team sharing stuff, I just want NVENC/etc.-based desktop streaming that doesn't bomb itself over the slightest system anomaly.
