Itch app uses more CPU% over long period of time

I noticed something weird. The issue is that if you leave the itch app running for a long period (a week) the app will slowly uses more and more of CPU % (as seen through Windows 10' task manager). It's like a memory leak, but for CPU.

I noticed this because I keep itch minimized in the tray and never turn off my computer for weeks. At start, itch uses 0% of the CPU when minimized. But after a week, it climb up to 17% of the CPU, still when idle, minimized in the tray.

I noticed this because when playing idle games, it's not unusual to leave the game open and running all day for weeks. In case it's important, the game I'm currently playing is Light Game ( I'm playing the Windows version, launched through the itch app (not the html5 version). And just to be clear, it's the itch app that uses more CPU, not the game.

I haven't tested if the issue occurs when leaving itch running for a long time but without having a game running too. If you think it's important, i would be glad to test that case for you. Or to send any logs or whatever you would like. I just want to itch app stay top quality (cause it LOVE my itch app!)


That's an interesting issue, I suppose we could record CPU usage over time (electron gives us that info), but I'll probably keep that investigation for after itch v25 is out, to see if it's still a problem.

Thanks for reporting though, it's good to keep an eye out as I, too, want the itch app to stay top quality :)

Is there anything you would like me to do? Is this forum the best place to fill "bugs" like that? I wanted to fill a real bug report but could not find where to place it.


There's still a fair amount of activity going on over at the itch issue tracker: - ideally we'd progressively move more and more to facilities so that having a GitHub account is not required!

I don't have anything in particular to ask you to do right now, but thanks for reaching out! We're nearing quite a big release, with lots of changes, so we want to finish that properly before we start looking again at various reports. I've also been looking at other issues like a half-dozen reports of folks who just aren't able to run the app due to bad antivirus interactions, those will probably be handled first!

I'm having this same problem. I dread starting the software because it slows my whole PC. Technically it still works, but I'm  usually unwilling to run it  because of this problem. For me, the high CPU usage begins immediately. I never let it run for very long because it makes my PC useless.
