High CPU usage on Ubuntu 22.04

[oaklsb]

Hello, I noticed Caprine using around 15-25% when idle on Ubuntu 22.04. Please let me know if you need more details. Thanks!

Same here, but 91%

Same on latest windows 11 lately

Same on Debian. Driving me nuts.

[mstapaj]

Same on Fedora 39. Higher CPU usage by about 5-10%

Kubuntu 23.10 flatpak same problem.

I am seeing the same in Debian 12. Initially the app has an expected usage and then after several hours of uptime it starts using more CPU, usually taking up 90~% of one core.

Restarting the application seems to help the problem.

Same @ arch linux. Eating one core.

[wkrska]

Same on Ubuntu 22.04.3 LTS, when application is in foreground it has one core pinned

I am having this issue too again. They fixed it in previous versions, but looks like the issue is back. Debian 12.

I have this problem too on Arch it uses around 4% of my CPU while all other apps in idle are not even close to that. But thing what concerns me the most is temperatures of CPU. In idle having discord and firefox open with multiple tabs I have CPU cores temps around 37C to 42C, but when I turn this caprine on it quickly raises to 42C-49C.Its quite a lot in my opinion.

I find out that it might be due hardware acceleration not working properly. I have set it on true on caprine setting, but when I run app in terminal I have this erorr:
libva error: vaGetDriverNames() failed with unknown libva error
I have it installed newest version.
Caprine right now runs fully on CPU not touching GPU data at all. so maybe all that stuff is being calculated on CPU that is not very effective I guess.

There is a pull request (#2110) ready which seems to fix the issue.

When running the below, the app opens and displays Messenger and then the screen turns white (this isn't an issue with "electron": "^28.2.1",. I noticed the CPU usage being low, but can't confirm usage.

Also, how do I build for a .deb package? I couldn't see that in the docs. Actually, npx electron-builder --linux

git clone https://github.com/bnabholz/caprine
cd caprine
git checkout fixes/high-cpu-usage

npm install && npm start

[phodamentals]

Same issue with CPU hitting at least 70% at all times while app is open.
OS: Pop!_OS 22.04 LTS
Caprine: 2.59.1

So here is what I did for a workaround solution for myself (so I can have it auto-pull into my repository server as well).

I forked this repo sindresorhus/caprine then pulled in the PR Fix: https://github.com/sindresorhus/caprine/pull/2110

I updated "electron": "^28.2.1" since that also was needed for me.

I also updated all the packages that could be updated without breaking.

Resulting in this: https://github.com/sgtcoder/caprine/releases

So maybe this could be a temp solution for now. It dropped my Intel CPU 20C.

Hi @sgtcoder . Could you test if #2109 fixes this issue. I suspect that the currently broken selector is causing elementReady to hang, resulting in high CPU usage.

I can take a peak later today :-)

Hi, I posted it here and I still had issues with it

For some reason though, updating electron and element-ready to the latest versions works well.

On my old Xeon machine driving a single core to 100%. Any hope for getting a fix soon?
