SUMMARY Widgets and the alt+tab popup no longer show any highlighting. OBSERVED RESULT No highlight is present on items in widgets. EXPECTED RESULT Hovered items should have a blue highlight on them. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.27.9 (available in About System) KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.112.0 Qt Version: 5.15.11 ADDITIONAL INFORMATION Logging out and then back in had no effect. Downgrading plasma-desktop back to 5.27.8 had no effect. Settings my theme and color scheme back up had no effect.
Running this command fixed it: ``` rm ~/.cache/{plasma-svgelements*,plasma_theme*} ```
