Confirmed in MC-264222. Can be reproduced in every update AT LEAST after 1.12.1 + many older versions, still in 1.20.1.
A fix is needed as soon as possible, as this negatively impacts the gameplay experience especially for people with GPUs that have less than 4GB of VRAM. Even I with 8GB, maxed it out in 25 minutes of exploring with a 32 chunk render distance, and then started stuttering.
Sodium is the only mod to my knowledge that fixes the leak, OptiFine doesn't, so preferably Vanilla's side should be the first to get fixed.
That is the exact issue I'm having. The Github link is in my bug report in blue text "here". There he describes the problem pretty similarly to MC-170134.
