Description lunatikovv 2019-10-15 09:32:03 UTC

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?

Comment 2 lunatikovv 2019-10-15 12:32:21 UTC

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)

Comment 4 lunatikovv 2019-10-16 09:33:04 UTC

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.
