When setting the Task Switcher to "Breeze Dark" the preview button has no effect and the actual task switcher when used is identical to the "Informative" switcher. STEPS TO REPRODUCE 1. System Settings > Window Manager > Task Switcher 2. Change Visualization to "Breeze Dark" 3. Click preview button to the right of the "Breeze Dark" selection 4. Click Apply 5. Press a configured task switcher shortcut such as Alt+Tab OBSERVED RESULT 3. nothing happens 5. same visualization as the "Informative" task switcher EXPECTED RESULT Probably "Breeze Dark" should not appear on this list at all. The "Breeze" task switcher already respects the colors of the Breeze Dark theme. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.14.90 KDE Frameworks Version: 5.54.0 Qt Version: 5.11.3
Can confirm.
probably related: task switchers from third-party look and feel themes are not working, the same behavior related here occurs: preview does not work and Informative task switcher shows up when I press alt+tab.

The Breeze Dark Task Switcher was deleted a few months ago, so the problem no longer exists.
