SUMMARY sometimes, randomly, the application launcher stops appearing when clicking the menu button (or pressing the WIN shortcut key). STEPS TO REPRODUCE 1. upgrade to 5.15.90 on arch linux 2. press the menu button quickly/repeatedly. OBSERVED RESULT the application launcher shows / hides repeatedly, but eventually it stops and no longer will become visible when the button is pressed. switching to a different alternative (application menu) restores functionality, but that launcher can then be broken in the same manner. sometimes plasmashell crashes and starts back up when pressing the button quickly enough. EXPECTED RESULT the menu / launcher should be very robust and always show / hide when the button is pressed. plasmashell should never crash. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (available in About System) KDE Plasma Version: 5.15.90 KDE Frameworks Version: 5.58.0 Qt Version: 5.13.0 ADDITIONAL INFORMATION
Actually, I seem to be able to make plasmashell crash by very quickly repeatedly clicking on system tray icons as well, but _not_ taskbar buttons, so I'm not really sure what the right component is.
additional information: if I click the launcher icon OR a plasma implemented system tray icon too many times, the popup (menu, launcher, network details, etc) stops showing up. this particular behavior seems to be harder to trigger with the system tray, because if I click too quickly, plasmashell actually crashes. I can also get plasmashell to crash by clicking the application launcher too quickly
I have the same problem with Plasma 5.16 beta on Arch Linux after update to Qt 5.13 beta4. I can reproduce dismissing the apps launcher by clicking outside it.
Dismissing the app launcher (or wif-fi selection, or any of the system tray popups) by clicking outside it is a better way to reproduce this issue. I should open a new bug for the plasma crash when clicking too fast then.

I am able to confirm problems OP, comment 1 and comment 4
Is everyone who's able to reproduce using Qt 5.13? I cannot reproduce with 5.12.

Seems like a Qt 5.13 regression. Please report upstream: https://bugreports.qt.io/ Thanks!
Has anyone in this bug report reported the bug to Qt devs? If so, can you share its link here please? The same problem is happening on Arch after update to Qt 5.12.4. Operating System: Arch Linux KDE Plasma Version: 5.16.0 KDE Frameworks Version: 5.59.0 Qt Version: 5.12.4
I am also affected by this. Also, I don't know if this is related, but the sliding animations in Plasma are extremely sluggish since Plasma 5.16 update : open the K Menu, go from "Favourites" to "Applications : the sliding animation is really slow and stuttery. ArchLinux, Plasma 5.16.1, Qt 5.12.14.
I meant Qt 5.12.4.
I have found this bug report https://bugreports.qt.io/browse/QTBUG-76657, is it this bug?

Mostly the last one for this specific bug.
Can anyone tell me if the following reproducible problems are duplicates please? open system seettings > Fonts, click any button to change a current font, click "Cancel" button. Click any button to change a current font again: nothing happens. click on the button to configure plasma panel aside the digital clock, click "Add widgets" button, close the Widgets Explorer. Now you can not open the widgets again following the same steps or via "Add widgets.." from the context menu of desktop.
