SUMMARY Each opening of external link in Electron based Slack produces hanged kde-open5 and xdg-open processes and CPU-load increases by 20%. Those processes recreate themselves if I try to kill them. Here are the the link to the same problem with Electron-based Microsoft VS Code. https://github.com/microsoft/vscode/issues/82430 STEPS TO REPRODUCE 1. Open Slack 2. Click the external link (to some website) OBSERVED RESULT kde-open5 and xdg-open processes created and CPU load increased by 20% EXPECTED RESULT Website is opened in browser or error message is shown. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian GNU/Linux bullseye/sid KDE Plasma Version: 5.14.5 KDE Frameworks Version: 5.11.3 Qt Version: 5.62.0 Kernel: 5.3.0-trunk-amd64 ADDITIONAL INFORMATION My current workaround is to make complete reboot.
Can you try opening the same URL with kde-open5 on the terminal and see if you get that increase?
I copied url from the app window and ran kde-open5 like this kde-open5 https://news.tut.by/culture/657418.html and it worked like a charm.
Additional info. Slack is installed from snap store and executed with parameter --no-sandbox (It will not load without this parameter)
It's not about Slack only. I have Slack, Skype and IDEA installed from snap and they all act the same: opening the link leads to those problems. I've checked journalctl and there is no messages there on click.
