Hope I’m doing this right. Apologies if not. I’m a slack novice.
I’m on Debian testing running KDE plasma 5.14.5. My slack version is “4.0.2 2019-08-21 (17) 153MB classic”
I updated and rebooted last Friday. Since then when I click on a link in slack nothing happens except my cpu usage goes up permanently. Every link clicked, another bump in cpu usage. Forget about this problem a few times and I have to kill and restart KDE.
Several KDE packages were updated last Friday so I’m not sure Slack is the problem. However, I can open links from other applications so I can’t say Slack isn’t the problem.
TBH looks like something is wrong with your KDE setup. Can you run xdg-open http://google.com inside the terminal (just your regular terminal, not a snap shell)? Does that open a web page?
Ah, I missed the fact that slack is a classic snap, in this sense it’s not really sandboxed in a separate filesystem view. Perhaps it’s best if you reach out to the maintainers of the snap, FWIW, snap info lists https://get.slack.help/hc/en-us as contact page.
