In which tab? Favorites, history, Applications, or something else? Or all of them? Can you see any kind of pattern? Asking because I cannot reproduce. Created attachment 120953 [details]
Application screenshot
I uploaded a shot of the application I'm talking about. Just to be sure I set the proper component in the report. I see the problem everywhere there is a square with something to click on. Even a widget. So I could reproduce in the "Favorites" section, in the "Recent applications" section, "Recent documents" and all the others I tested (I can't find the "history" tab you referred to). Unfortunately I cannot find a real deterministic pattern: may need 1 click, 2 clicks or more. Sometimes I simply gave up. But the "enter" key always works immediately. I'm a dev, can I help somehow? Any log I can enable? Can I start that from the command line somehow? If you want me to add a log somewhere and test I can probably do it if you give me some hints. It seems I cannot reproduce on the buttons "Apps & Docs" and "Widgets". Ah, Application Dashboard, not Kickoff. Still cannot reproduce unfortunately (fortunately?). I would recommend doing a git bisect on the plasma-desktop repo, where this lives. Also take a look at applets/kicker/package/contents/ui/ItemGridDelegate.qml I'll try to bisect. Did you try on a HiDPI screen by any chance? No, regular DPI (1920x1080). I tried to simply disable nVidia and run on Intel HD only. No issue on Intel HD. The problem occurs only on nVidia. Unfortunately I tried to create a VM to rebuild plasma and run a session there but... believe it or not, virtualbox freezes the system when on nVidia... So, I don't exactly now how to help more on this. Moving to KWin for comment. Possibly an upstream bug. Are you using the proprietary drivers? Does it happen on Wayland too, or just on X11? Yes, proprietary drivers. I only use X11 as kwin with wayland on nVidia is not supported (probably added in 5.16 right?). Right! Tried Plasma on Wayland with nVidia: I could reproduce immediately. If you run an application from the terminal, does it show up immediately? I don't understand why this was moved to KWin. It's clearly not a bug in the window manager as it's not involved with input handling on X11. @Vlad yes, starting apps from command line works properly. The only thing not working properly is the "click event" in that view. Someone who can suggest a way to debug this? I was able to build everything and log into a dev version of Plasma. I suppose it is difficult to use gdb in there. Can I read logs somehow from that QML file or from the component? It seems that the issue appeared in 0ecb135. This is my attempt to fix the issue: https://phabricator.kde.org/D22306. It seems to work so far in my environment: applications are properly opened when clicked, moving an icon to the favorite list does not close the dashboard and also clicking outside results in closing the dashboard. Unfortunately, the rationale behind that commit is not completely clear to me. In particular, this line https://phabricator.kde.org/source/plasma-desktop/browse/master/applets/kicker/package/contents/ui/ItemGridView.qml$433 is not completely clear to me. It seems my env has something peculiar, as no one else could reproduce. Maybe there is someone who can review my patch and let me know if it works? Thanks. *** Bug 409625 has been marked as a duplicate of this bug. *** Git commit fba194e562730e4b038a231330b9d45c331f8535 by Nate Graham, on behalf of Luca Carlon. Committed on 24/07/2019 at 19:50. Pushed by ngraham into branch 'Plasma/5.16'. Do not skip code launching application in application dashboard Summary: Since Plasma 5.16, clicks over the icons are frequently ignored. See https://bugs.kde.org/show_bug.cgi?id=408748 for more info. This patch is an attempt to fix that seems to work for me.
