I am unable to get hardware video decoding (NVDEC) working on Opera One under Ubuntu 26.04 LTS with a Wayland session and an NVIDIA GPU. Video streams (such as Twitch streams) fail to offer higher resolutions like 1440p (2K), and decoding falls back entirely to software (CPU).

Here are my full system and browser details:

System & Browser Specs:

OS: Ubuntu 26.04 LTS x86_64 (GNOME / Wayland session)

GPU: NVIDIA GeForce RTX 5070 Ti (Proprietary Drivers)

Browser: Opera One (Version: 133.0.5932.85, Update Channel: Stable)

Chromium Engine Version: 149.0.7827.201

Observed Issues & Logs (opera://gpu):

Under Video Acceleration Information, the Decoding and Encoding sections are completely blank.

The browser automatically skips the NVIDIA device for VA-API:
WARNING: media/gpu/vaapi/vaapi_wrapper.cc: Should skip nVidia device named: nvidia-drm

Ozone Wayland throws an incompatibility error with Vulkan:
ERROR: ui/ozone/platform/wayland/gpu/wayland_surface_factory.cc: '--ozone-platform=wayland' is not compatible with Vulkan. Consider switching to '--ozone-platform=x11' or disabling Vulkan

DRI permission errors are logged on startup:
MESA-LOADER: failed to open dri: /usr/lib/x86_64-linux-gnu/gbm/dri_gbm.so: Permission denied

Note: The #ozone-platform-hint flag is missing from opera://flags on Linux, so forcing Ozone behavior via the GUI is not possible. Launching via terminal with flags like --ozone-platform=x11 or --ozone-platform=wayland still results in Vulkan conflicts or MESA DRI permission issues.

Is there a recommended configuration or flag setup for Opera One on Ubuntu 26.04 LTS to bypass these driver blocklists and correctly hook into NVDEC / VA-API under Wayland?

Thanks in advance for your help!
