Modrinth launcher lags and loads one of the cores at 100% on Linux

[Rikopara]

Describe the bug

I've tried both flatpak and .deb versions. Whenever I scroll or click, it's really laggy and sometimes even freezes until I end the process manually. One of CPU cores (always different) starts to load at 100% until I stop scrolling.

I am also experiencing this bug. I notice that practically any action causes this behavior making me wonder if it's an animation issue, since they seem to be stuttering. Opening the logs tab crashes the app as well. Since this is open source, I may do some tinkering around with it and see if I can find the root cause...

I have the same problem. Actually, scrolling does not bother me much, but the button animations are very slow.

Indeed, as mentioned in tauri-apps/tauri#6200, building from source (in both debug and release profiles) fixed the scrolling issue.

Weird as when I use the modrinth-app aur package which I assume is building from source I still get terrible scrolling.

same issues here
Package: modrinth-app-bin from aur

Intrestingly enough does the problem only accure on the first few pages for me 🤔
IDK, but I feel like the popularity of projects could affect the performance
Like for real it could be releated to some issues with bigger data types in Tauri

EDIT: After @AsaTheUncle said that he had issues with opening the logs I remebered that I had too.

I don't want to build it from source. Are there any solutions yet?

Same issue on SteamDeck OLED 1TB (SteamOS 3.6)

Very Laggy UI, one CPU core 100% usage.

[sinzek]

Issue still persists on linux mint (Cinnamon)

[pokahs]

Also having this issue on debian 12... any solutions?

[Rikopara]

I've noticed that different modrinth packages also behave different. For me (Fedora 41) RPM works just fine, but appimage is extremely laggy. So, as possible solution, you may try every package your system supports, or even build modrinth from source. Hope this helps.

I might try to use flatpak, see if thats better... but right now I'm having this issue with deb and appimage, as well as some weird seg fault issue with deb.

Edit: Tried flatpak, got exact same problem...

Also getting constant crashes with either app image, .deb, and flatpak whenever I try to navigate to logs, folders, etc. Ubuntu 22.04 Distro
