Yes, Firefox still doesn't enable HW compositing by default on 
Linux/BSD/etc.

You have to force-enable it in about:config (or via environment 
variables).

To clear some confusion:

- VA-API is, well, an API. For video encode/decode acceleration;
- Mesa has a VAAPI implementation for AMD Radeons;
- libva-intel-driver is a VAAPI implementation for Intel iGPUs — it's 
*not part of Mesa*, it's an independent Intel project;
- Gallium is an internal graphics-related part of Mesa that doesn't 
have much to do with VAAPI.
