SUMMARY
***
I have laptop with AMD iGPU and nVidia GPU. I'm using proprietary nVidia drivers. I'm using hybrid mode.
***

STEPS TO REPRODUCE
1. Play any video with Haruna.

OBSERVED RESULT
When paying a video, both GPUs are used. You can see it on screenshot. When I play video in mpv, only one is used (AMD iGPU).

EXPECTED RESULT
Only one GPU should be used.

Just found out that when I disable hardware decoding, it works the same as mpv. And mpv is not using hardware decoding by default, it seems. So I have to look for a solution to force using iGPU instead of nVidia.
