Essentially, all it takes to trigger the bug on my system is: 1. Open 2 or more instances of the same application - in this example, Konsole. Hover over that app's icon in the panel until the preview window appears, then click on that preview to display all the available windows in the 'selector' view. Click on one of the Konsole windows to select it, which closes that view. 2. Move the cursor to the Pager, and hover over the virtual desktop box containing those Konsole windows. 3. Move the mouse cursor back to the app's icon in the panel and enjoy the bug. I regularly have 2 or more instances of the same application open (Firefox windows, Pycharm, etc). I wonder if the following environmental variables are essential to trigger the bug: * Multiple instances of the same application. * Multiple desktops, with the Pager widget displayed on the Panel. I'm not sure whether to open a new bug with for Pager, referencing this one, or somehow add Pager to the component list for this bug ... hopefully someone involved with the project will see this and chip in with guidance. Not sure if this is significant, but running Plasma Shell from CLI shows a lot of these errors being written to STDOUT / STDERR org.kde.plasmaquick: Delayed preload of "Device Notifier" after 6.009 seconds org.kde.plasmaquick: Applet "Device Notifier" loaded after 33 msec QXcbConnection: XCB error: 2 (BadValue), sequence: 2254, resource id: 109051913, major code: 142 (Unknown), minor code: 3 file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/ToolTipInstance.qml:41: ReferenceError: AppPid is not defined file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/ToolTipInstance.qml:36: ReferenceError: index is not defined file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/ToolTipInstance.qml:181: ReferenceError: IsMinimized is not defined QXcbConnection: XCB error: 2 -- You are receiving this mail because: You are watching all bug changes.
