Screenshot: some icons are normal - 3

After restarting Discovery, some icons could appear (compare with https://bugs.kde.org/attachment.cgi?id=174549)

Actually, I believe it does not happens on Fedora.

Found this thread: https://www.reddit.com/r/openSUSE/comments/1bxqa6n/no_program_icons_in_discover/

Cannot reproduce in Fedora 40 KDE. All the icons load for me.

It seems it is a openSUSE bug...

Right now icons are loading fine on openSUSE.

Updated openSUSE and restarted. Again blue icons... :-/

Please run

>  QT_LOGGING_RULES=org.kde.*=true plasma-discover &> log

wait about 1minute

then attach the file 'log' to the bug report.

It makes an 0 sized file...

BTW I made a bug in openSUSE bugzilla:
https://bugzilla.opensuse.org/show_bug.cgi?id=1231586

Run just: QT_LOGGING_RULES=org.kde.*=true plasma-discover

First run - all icons were present:

Two weeks ago I have posted the logs.

KDE 6.2.4. Still the case on OpenSUSE Tumbleweed (and still not always), no problem on Fedora 41.

Installed to a VM Fedora 41 Kinoite and see the same problem...

CCing Timothée to maybe have a look into this. It seems to work fine for me on KDE Linux, maybe there is something platform specific going on here.

I'm aware that this happens on Fedora Kinoite (see: https://pagure.io/fedora-kde/SIG/issue/136) with Fedora Flatpaks only. I don't use them so I'm not working on this.

What I think happens is that we fail to look up the stock icons. Of course there is a downstream component to this as well in that we shouldn't need to rely on stock icons since they will not have 100% coverage. i.e. the affected distros need to ship cached icons or remote icon uris in their appstream data.

A possibly relevant merge request was started @ https://invent.kde.org/plasma/discover/-/merge_requests/1025

I still see the same problem on Tumbleweed.

First start of Discover - OK.
Second start - blue icons.
