High CPU usage
After a while of running I'm seeing incredibly high CPU usage from trayscale. This is on Fedora 37 using the latest flatpak, 0.9.7.

It's eating approximately 2 cores of a Ryzen 9 7950x.
According to strace it's not doing very much...

I know this is a bit vague but I'm not sure what else to provide.
I can not replicate it. Even when I'm actually actively using the app, the CPU usage never reaches even 1% for me on either my 12 core desktop or even my 4 core laptop. Is there any other information that you can provide? How long is 'a while'?

I tend to notice it after a couple of days. I can recreate it on 2 machines consistently so far. The Ryzen 7950x I mentioned earlier where I tend to not notice because what's 2 cores out of 32...
But my laptop does it was well, also Fedora 37 using latest Flatpak. It causes the fans to ramp up so I tend to notice it quicker there.
Hmmm... I haven't tried running it continuously for more than a day. I rarely leave my computers running overnight at all, actually. I'll see what I can do.
Still able to recreate it on Fedora 37.

Have you had any luck recreating it when leaving your machine running?
Out of curiosity, have you tried to disconnect from the server (while keeping the application open) while this is happening, and if so, does the CPU usage persist?
@jonathanspw
Not yet. I'm trying to find a good few days to leave my computer running. It's very much outside of my normal workflow, but I may have some days that'll work coming up.
@codyro
If you're talking about disconnecting the Tailscale daemon from the tailnet, that probably won't help, unless the problem is happening with the connection between Trayscale and the daemon. The daemon is a completely separate process that isn't even started by Trayscale, so high CPU usage on its side won't show up as high CPU usage by Trayscale.
I left Trayscale running continuously for over 60 hours. This is the result:
The memory usage is quite high, possibly related to a number of potential memory leaks that I've been trying to track down for a bit now, but the CPU usage is completely normal. I'm not sure why you're seeing abnormal CPU usage. When you left it running, was the window displayed most or all of the time, or was it hidden with just the tray icon visible?
