Bug ID: 426672
Summary: Running many docker containers makes Dolphin unusably
slow
Product: dolphin
Version: 20.04.0
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

SUMMARY
Hi,
I just switched to Kubuntu 20.04 from Ubuntu 18.04 and everything started
smoothly. I want Kubuntu to be my new dev system and I need Docker.
Dolphin, however proofed to be unusable when using docker, as it displays
containers as devices which makes it freeze for a few seconds, every time that
it is focused.
According to a reddit post, I've found https://phabricator.kde.org/D22080 is
the culprit for this behavior. I have reverted the patch and rebuild and
installed solid and the docker containers are still listed as devices (which I
personally don't want, although I can live with it and can follow the argument
for having them there), but Dolphin stays responsive.
STEPS TO REPRODUCE
1. Freshly install Kubuntu 20.04
2. Start a bunch of Docker containers
OBSERVED RESULT
Dolphin slows down significantly, needing several seconds before being
responsive
EXPECTED RESULT
My file manager being responsive when switching to it.
