Suggestion: enable hardware video decode (VAAPI) flags for Brave/Chromium by default

[ayushdecoded]

Problem

On Omarchy 4.0.1, Brave ships without any hardware video acceleration flags (~/.config/brave-flags.conf has no VaapiVideoDecodeLinuxGL). On a laptop with an Intel/AMD iGPU, YouTube and other VP9/AV1 video decodes entirely in software — a single paused-but-open YouTube tab was pinning ~100-130% CPU (8 CodecWorker threads) on my machine.

Suggestion

Ship these two lines in the default ~/.config/brave-flags.conf:

--enable-features=VaapiVideoDecodeLinuxGL
--disable-gpu-driver-bug-workarounds

These are safe no-ops on systems where VAAPI is unavailable, and give a large battery/performance win where it works (YouTube CPU drops to ~15-30%).

Caveat for NVIDIA-only systems

NVIDIA does not support VAAPI natively; users would need nvidia-vaapi-driver from the AUR. So this helps iGPU/hybrid laptops most, which are probably common in the Omarchy audience. Worth documenting either way — even a wiki note about enabling hw video decode would help.

Happy to test a PR if there is interest.
