Icon-Only Task Manager tooltips show grouped windows without a title on mouse hover. It would be great if they were to show window title to easily distinguish between them. Reproducible: Always Actual Results: Grouped window preview is shown without window title in Icon-Only Task Manager tooltip Expected Results: Window title should be shown when previewing more than one window in the Icon-Only Task Manager tooltip
Created attachment 98108 [details] screenshot of grouped window preview
I can confirm this behaviour on the latest applications release (5.6.4). I think this could be considered an usability issue and code bug. I think that the default behaviour should be that when you hover on a selected window, the generic title on the bottom of the group to be replaced with the window title.
We show the window titles now as of KF 5.31/Plasma 5.94, at least.
