Created attachment 135715 [details] Screencast I was trying to remove a repo. The instructions at https://help.ubuntu.com/community/Repositories/Kubuntu are outdated, as there are no trash can icons. It took me quite a while to figure out that "Software Sources" was a button and not a label. I use the Fusion app style, and the Kubuntu theme.
Not having an icon is a big part of the problem here. The lack of one may be our bug. However it's also supposed to have an outline that appears on hover when you move the cursor over it. I didn't see that in your screen recording, but it could be a low FPS issue with the video file. If you don't see it either, that's a bug with the Fusion style. In the past, these buttons were implemented as PushButtons to ensure clickability even when there was no icon, but it looks like they got changed to ToolButtons in the port to Kirigami.ActionToolbar, which implements its buttons always using the ToolButton style.
Nope, don't see any outline on hover either. Thanks for confirming!
I cannot reproduce. Can you try running Discover with QT_QUICK_CONTROLS_STYLE=Material set?
