Línea de trabajo

Start by comparing the provided cannot_stream.log and can_stream.log files in the linked Gist, focusing on the KMS capture errors and repeated encoder creation. Reproduce the failure on a Wayland session with the reported AMD GPU and Mesa setup, then trace the failing capture path. Done means streaming starts normally without the EGL_BAD_MATCH loop.

This issue is present in the latest pre-release

Describe the Bug

Here are the reproduction steps.
Step 1: Run sudo mkinitcpio -P in the terminal to regenerate the initramfs.
Step 2: Reboot the computer and log into a Wayland session.
Step 3: Start the Sunshine application.
Step 4: Connect using a Moonlight client.
Step 5: The connection times out and disconnects; Moonlight does not receive any video stream.
Note: If I skip Step 1 and just reboot the computer directly, this disconnect issue still occurs with a probability of about 1 in 20.
For the specific error logs and the infinite loop behavior, please refer to the online logs provided below.

Expected Behavior

Sunshine should stream video normally.

Additional Context

The provided Gist contains two files.
cannot_stream.log is the Sunshine log captured when streaming fails.
can_stream.log is the kernel log captured when streaming works normally.
