High CPU usage running under asahi-linux

[8RATH]

Describe the bug
A clear and concise description of what the bug is.

Moonlight use about 30% of my CPU despite it is not connected to anything.

Steps to reproduce
Any special steps that are required for the bug to appear.

1. Grab a apple silicon device (mine is a M2 MacBook Air), run asahi linux (Fedora Remix) on it, then install moonlight via flatpak.
2. Try to launch the moonlight app
3. without connecting to any stream, look at moonlight's CPU usage

Other Moonlight clients

• Does the issue occur when using Moonlight on iOS or Android?

No

Moonlight settings (please complete the following information)

• Have any settings been adjusted from defaults?
• If so, which settings have been changed?
• Does the problem still occur after reverting settings back to default?

I tried different codec settings (Force Software Decoding, Force H264), does not seem to affect the problem. Other than this, everything is default.

**Client PC details

client OS: Asahi Linux Fedora Remix
Moonlight version: v6.1.0
GPU: Apple M2 GPU
Linux package type: Flatpak

Server PC details (please complete the following information)

Server not needed. Can replicate this issue without connecting to any server.

Moonlight Logs (please attach)

Moonlight use about 30% of my CPU despite it is not connected to anything.

I wonder if this is because it's using llvmpipe and rendering on the CPU. Can you try running it with the following command which will print out the GL driver in the logs:

flatpak run --env=QSG_INFO=1 com.moonlight_stream.Moonlight
