--- Comment #99 from Knut Hildebrandt <knut.hildebrandt at gmx.de> ---
Updated KDE Frameworks and nothing seems to have changed. I even got the
impression it got worse. Hibernated the machine last night, what brought all
dolphin instances back to below 100 MB each, but now about three hours later
three of them are in between 0.5 and 1 GB, four between 100 and 500 MB and only
two below 100 MB. And Ooe of the ones above 500 MB sometimes uses between 10
and 15% CPU. BTW, the more CPU time an instance has accumulated the higher the
memory it occupies.

I still double click all files - including video and audio - to open them. Only
exceptions: audio playlists which I open from amarok and if I do not want to
open a file in it's standard application.

One change I noticed, sometimes memory seems to get released. But if I'm not
mistaken, this effect I already noticed earlier, for instance with Frameworks
5.82.0.

Operating System: Manjaro Linux
KDE Gear Version: 21.04.3
KDE Plasma Version: 5.22.3
KDE Frameworks Version: 5.84.0
Qt Version: 5.15.2
Kernel Version: 5.10.49-1-MANJARO (64-bit)
Graphics Platform: X11
