probably related but on a fresh install of 23.5 jammy, hardware acceleration is enabled but hardware video decode isnt in chromium - this solves the hw video decode problem with sd videos having a green screen. in your glxinfos it says "Accelerated: yes". i just assumed a developer disabled the hw video decode becuz i doubt the ppa video drivers will ever get updated so that green screen bug is there forever until mainline video drivers happen (which i imagine will also take forever).
