additional multimedia codec required an application is requesting additional multimedia codecs sometimes I get this popup message and there is no way to close it as it keeps popping up and plasmashell starts eating up all the memory and high CPU usage the only fix is a restart. Linux lenovo-p50 4.14.14-300.fc27.x86_64 #1 SMP Fri Jan 19 13:19:54 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux I think it set to use x11 The same happens under KDE and Gnome very similar to this bug https://bugzilla.gnome.org/show_bug.cgi?id=767809
GNOME no longer uses notification-daemon; on which desktop(s) are you seeing this?
KDE , but the same happens on gnome
Created attachment 1403330 [details] screenshot when I click "Find Software" another message pops up - "Software crashed."
Created attachment 1403331 [details] high mem and cpu load after this message the cpu and mem starts growing until I restart the laptop
This has nothing to do with notification-daemon, as it wouldn't be used in either GNOME nor KDE Plasma desktops. You will need to reassign this to the component providing the application causing this notification.
ok thanks any idea how to find out which this component is?
