SUMMARY STEPS TO REPRODUCE 1. Open Discover 2. Select Plasma Addons 3. Select Wallpapers OBSERVED RESULT Empty page, with "Still looking" animated throbber on bottom. I checked that for 10 minutes. EXPECTED RESULT Wallpaper list or message about wallpaper unavailability SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.14.3 KDE Frameworks Version: 5.52.0 Qt Version: 5.11.2
I'm not experiencing this issue on Neon Dev Unstable. However, I am seeing that sometimes when I click a category (plymouth, wallpapers, etc.) I get stuck with loading, but results come up if I click another category then back to the original category.
Something interesting I noticed is that this behavior seems to happen when normally starting discover (i.e. using a panel), but I'm unable to replicate this behavior when running `plasma-discover` in konsole.
I ave the O.P.'s exact issue in Plasma 5.14.4. (Neon User). For reference, when run from the command line, the relevant terminal output is the following: "org.kde.plasma.libdiscover: last stream isn't over yet Filters(category: Category(0x55a12dadeb50, name = "Wallpapers"),) ResourcesProxyModel(0x55a12f99d680)" Hope this helps.
This should be fixed please test on 5.15 and reopen if it's not the case.
