The Task Manager option, "Open groups in popups", produces a vertical list of windows for the group (e.g. by program name), which only shows entries. The rendering of the last in the list appears to be below the taskbar. Open users have many more windows open for a program than 15, for example many more Dolphin windows, which can serve as a reminder for various tasks. The inability to scroll this list means that all windows cannot be accessed from the taskbar when grouped. Not grouping with a large number of windows causes each window to have a very tiny icon which is almost indistinguishable from the others. Scrolling through a large number of ungrouped windows in the taskbar, even with tooltips, is very time consuming. Another option, the Window List which has a scrollable popup, does not have the ability to group windows by program name, and in fact has no settings at all. This happens even if the "maximum rows" is set to 99. (Apparently this has nothing to do with the popups.) A simple solution is to have the popup list be scrollable when the list exceeds a certain number or height.
Please specify your version number. That dialog was rewritten for Plasma 5.9 and is now scrollable.

I confirm, the same bug is still in Version 21.04.3 :-), just hit accidentally, an annoying thing - the regression from the previous KDE releases Now how you can fix it: 1. Copy /usr/share/plasma/plasmoids/org.kde.plasma.taskmanager to ~/.local/share/plasma/plasmoids/org.kde.plasma.taskmanager/ 2. Open ~/.local/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/GroupDialog.qml and change readonly property int preferredHeight: Screen.height / (2 * Screen.devicePixelRatio) to readonly property int preferredHeight: Screen.height / (1 * Screen.devicePixelRatio) this will give you the full screen height for the grouped tasks You may all so want to change readonly property int preferredWidth: Screen.width / (3 * Screen.devicePixelRatio) to readonly property int preferredWidth: Screen.width / (2 * Screen.devicePixelRatio)
And while I was looking through GroupDialog.qml I found another bug. to see the bug set: a. task grouping set to at least "By program name" (irrelevant though) b. clicking grouped text set to "Show textual list" open 5 konsoles, they should be stacked and popuped as 5 terminals normally when clicked on konsole icon in the task bar now open any 2 identical tasks that would stack into one group say chromium And now the bug: First click on konsole icon - 5 items would popup normally Now click again on konsole icon - 5 items would close normally And now click on Chromium icon - you will see that the popup opens with 2 chromium tasks but the height of this popup would be the same as the height of the previous grouping popup that contained 5 konsoles - an ugly looking thing How to fix it: 1. override the system org.kde.plasma.taskmanager with a the local copy like with the previous fix or skip this if you already have a copy of it in your ~/.local/share/plasma/plasmoids/org.kde.plasma.taskmanager/ 2. open ~/.local/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/GroupDialog.qml find onVisualParentChanged: { if (visible && visualParent) { attachModel(); } else { visible = false; } } and change it to onVisualParentChanged: { // Fixed updateSize(); if (visible && visualParent) { attachModel(); } else { visible = false; } } that's not all, find onVisibleChanged: { if (visible && visualParent) { _oldAppletStatus = plasmoid.status; plasmoid.status = PlasmaCore.Types.RequiresAttentionStatus; attachModel(); groupDialog.requestActivate(); mouseHandler.forceActiveFocus(); } else { plasmoid.status = _oldAppletStatus; visualParent = null; groupRepeater.model = undefined; groupFilter.model = undefined; groupFilter.rootIndex = undefined; } } and change it to onVisibleChanged: { // Fixed updateSize(); if (visible && visualParent) { _oldAppletStatus = plasmoid.status; plasmoid.status = PlasmaCore.Types.RequiresAttentionStatus; attachModel(); groupDialog.requestActivate(); mouseHandler.forceActiveFocus(); } else { plasmoid.status = _oldAppletStatus; visualParent = null; groupRepeater.model = undefined; groupFilter.model = undefined; groupFilter.rootIndex = undefined; } } and that will fix the annoying bug with the wrong height of the window that allocates stacked (grouped) tasks
