Following the recent update to kde-frameworks-5.17.0 / plasmashell 5.5.1 the widget explorer is not being populated. (Screenshot 1) All widgets are present in /usr/share/plasma/plasmoids Curiously, if I "guess" the location of a widget (within the explorer) I am able to grab and drag it using the mouse. (Screenshot 2) Reproducible: Always Steps to Reproduce: 1. Unlock widgets 2. Add widgets 3. Actual Results: Empty unpopulated widget explorer sidebar opens. Expected Results: The widget explorer is populated with available widgets :) Desktop theme: openSUSE Widget style: QtCurve Window decoration: Oxygen Icon theme: Oxygen Ionised Prior to the update to kde-frameworks-5.17.0 / plasmashell 5.5.1 the widget explorer was working correctly using the above set-up.

Could be a repaint issue due to the opacity animator that fades the list in?
Comment 5 by Kai Uwe Broulik is, it would seem, is very relevant... I'm far too old for all these fading, zooming, or sliding animations, and have them disabled via setting "longDuration=0" in "~/.config/plasmarc". (As per Sebastian Kügler https://quickgit.kde.org/?p=plasma-framework.git&a=commit&h=52c489eee50621aebb8fd7c57bce7f327a602ad8 ) It seems that the Widget Explorer code is not handling that very well. If I temporarily remove "longDuration=0" then the Widget Explorer shows the widgets. Now, please, before you dismiss this as a 'WONTFIX', I would like to point out that disabling animation is something that some users would wish to do. A Google search on the phrase 'disable kde animations' just returned "About 33,100 results", so I don't think you can legitimately say that I'm a statistical outlier :)
Could be that the animation is fired before the window is visible at which point it fails to get an animation context and breaks. I've seen this elsewhere, too. I think that's also the reason the busy indicator won't spin (eg while connecting to wifi) right after Plasma startup. Looks like a Qt bug I haven't managed to find a simple way to reproduce but in widget explorer a workaround should be possible.
Created attachment 96487 [details] Hack for opacity animator Can you try whether thix patch fixes this for you?
Ah, wait, sorry. I know why. Animators do not like a duration of zero, hence the breakage for you. Sebas/Marco: I think we should have animation duration retur at least 1ms, no matter what is set, to work around this, we have other places where we use Animators bound to the units durations.
Upstream bug report: https://bugreports.qt.io/browse/QTBUG-39766
First off -- Thanks. :) I've changed the setting to "longDuration=1" in "~/.config/plasmarc" and that works well. Visually, animation is "disabled", and widgets are now shown in the Explorer. Win / Win - Animation for the (probable majority) who want it - No animation for old farts like me.
