Credits go to [Kurt Wilson](https://github.com/Kurtoid) for this idea! #### Other Enhancements * On KDE, the effect configuration dialogs can now be translated. The translations for GNOME are re-used, so we already have many translations! This requires at least KWin 5.27 to be working. +* The effect colors for the Glitch and TV Effect now support an alpha channel.
