In versions prior to 5.5, such as 5.4, there was a thin line above an application name indicating the active window and eventual notifications. Personally I prefer the old style, it somehow feels smoother and less obtrusive, probably because it uses less colour. I would appreciate if one could select the style he wants, perhaps through the task manager configuration. Screenshot of old style from YouTube thumb: https://i.ytimg.com/vi/FKAyy4Gfxrs/maxresdefault.jpg Reproducible: Always Steps to Reproduce: 1. Update from Plasma 5.4 to 5.5. Actual Results: Task manager style is different with no way to change it. Expected Results: Task manager style is different, but old style can selected through options.
I think you can find the Plasma 5.4 theme on "Get New Themes".
Thanks for the quick reply, I managed to work out a solution that only changes the bask bar but leaves everything else. For anyone that wants the same in the future (only old taskbar, everything else new): 1. Open "Desktop Theme" settings. 2. Go to "Details" tab. 3. Tick "More" at the bottom. 4. Select desired theme and export it. Unzip it and change directory name to new-theme-name. 5. Edit "metadata.desktop" and set "X-KDE-PluginInfo-Name" to "new-theme-name". 6. Download and unzip only the classic "widgets/tasks.svgz" into "new-theme-name/widgets/tasks.svgz". - https://opendesktop.org/content/show.php?content=174360 (Breeze) - https://opendesktop.org/content/show.php?content=174361 (Breeze Dark) 7. Zip the "new-theme-name" directory. 8. Import the newly created zip file in the "Desktop Theme" dialog.
