Every time I open qbittorrent it slowly more and more memory util it runs out.

Does that happen to someone else?

Interesting, you might be running into an actual bug that may need to be fixed. There's mention of something similar over in the qBittorrent Github issues e.g.

https://github.com/qbittorrent/qBittorrent/issues/25202

That particular bug report mentions Debian, same as me, but I haven't run into it so am not sure what triggers the issue. But my Debian installation has an updated Linux Kernel so I wonder if that has something to do with it.. I'm on 7.2.11, Debian Stable is on 6.12 I believe. Just out of curiousity do you know which Linux kernel version you're on? In terminal just run

uname -a

To potentially work around the issue, if it's just something with the latest qBittorrent, you could try downgrading to an earlier version. I've never used Bazzite but I assume it allows you to run AppImage binaries - You can grab earlier version qBittorrent .appimage binaries from their Sourceforge page linked at https://www.qbittorrent.org/download (after download you'd need to chmod +x the .appimage file to actually be able to execute it).

Barring all that, lowering your maximum connections / bandwidth could be worth a try since that should lower the overall RAM requirements for qBittorrent/Libtorrent at runtime.

PS - Back up your qBittorrent settings folders before any downgrades/upgrades

    Ugh I guess we can rule out the Linux Kernel version, at least we know that's not the issue.

    I'm not familiar with Bazzite but I think(?) it grabs and updates apps through Flathub (per https://docs.bazzite.gg/Installing_and_Managing_Software/Flatpak/) so another idea is trying the qBittorrent appimage from the qBittorrent devs, instead of the version that qBittorrent binary Bazzite gives you, just to test & see if there is any difference. That should at least rule out some specific issue with the qBittorrent binary in Flathub. (In theory it should work the same)

    Might be out of ideas beyond that :/ You can try posting in qBittorrent's Github, maybe it's the same bug some other people are running into.
