                    apps

SUMMARY
In electron apps like element, slack, signal I observed hangs recently occuring
more or less random (but usually after interaction). In the journal I see on
every hang the message "Failed to connect to proxy" and then the application is
blocked. After some time, the app resumes. This didnt happen with kde5.

According to the logs this seems to be related with notifications:
