The Issue

I'm streaming games from a desktop PC hardwired into my router (running Sunshine) to a laptop wirelessly (using Moonlight). It works beautifully.

Except, every five minutes, the stream chugs: my framerate drops precipitously, and Moonlight gives me a warning telling me I should lower my bitrate. This happens for only a few seconds, before it resolves and goes back to normal.

I timed the interval between the chugs several times and got approximately 5:07 between each slowdown. It is remarkably consistent.

Because it's so consistent, I assume there's some scheduled task or something running every five minutes that's causing it to chug. Dropping the bitrate makes the chugging less noticeable, but it still happens.

Ruling Things Out

I think it's safe to rule out the idea that it's my router or the host PC.

I have a smaller 13" laptop that I used to stream to, and I just recently bought a 17" to replace it. The five-minute issue only happens on the 17", even with identical stream settings (same resolution, FPS, and bitrate).

The computers are obviously different hardware, but they're also running two different linux distros.

The 13" Laptop is running MX Linux 23.5 (KDE). This is the one that works.

The 17" Laptop is running Linux Mint 22.1 (Cinnamon). This is the one that has the five minute chugs.

Help Request

Anyone have any ideas for tracking down what might be causing this? I was going to just wipe the machine and replace Linux Mint with MX Linux to rule that out, but I figured I'd ask here before doing that, especially because it could be the hardware and not the distro that's causing the issue.
