Bug ID: 457408
Summary: Opening discover is still horribly slow
Product: Discover
Version: 5.25.3
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Notifier
Assignee: plasma-b...@kde.org
Reporter: zi...@kayari.org
CC: aleix...@kde.org
Target Milestone: ---
There's still something wrong with the Discover UX, despite Bug 443555 fixing
the worst source of slowness.
If I get a systray notification that there are updates, and I click on it, it
takes 30 seconds to stop showing the "fetching updates" progress bar. Why? Is
it refreshing something? It doesn't seem to be, because it still tells me I
have system RPMs to update, even though I've already updated them on the
command line with dnf. So it's not refreshing the packagekit backend, otherwise
it would know that the updates have been installed.
The available backends are:
$ plasma-discover --listbackends
Available backends:
* kns-backend
* packagekit-backend
* fwupd-backend
* flatpak-backend
If I run 'plasma-discover --backends
flatpak-backend,packagekit-backend,fwupd-backend' then the window loads
instantly, and takes less than a second to finish "Fetching updates" and show
"Up to date" at the bottom left corner.
If I add kns-backend to that list, the window opens but shows "Fetching
updates" and is completely unresponsive for 30 seconds. Is that the same
problem as when I click on the "Updates available" notification?
What even is KNewStuff, and what do I miss out on if I disable it?
