Impact: SteamVR wouldn't use the HEVC encoders in the RX6750XT and Kdenlive cannot encode a 1080p video faster than 40fps.
From the original report
“Unfortunately it's all AMD - not sure why VAAPI isn't working correctly. I specifically switched from Mint to Cachy because SteamVR wouldn't use the HEVC encoders in the RX6750XT - yet now Kdenline can't encode a 1080p video faster than 40fps.”
