Hello!
Do you hate the watermark preview banner?
Add the text HideDesktopPreviewBanner=true just after [] in the file ~/.config/kdeglobals. You will have something as the following:
[General]
HideDesktopPreviewBanner=true
Better for OLEDs displays, stylish, auto-suspend all-blacks displays, etc.
How could “tHe OpEnSouRcE ComMunItY” dare to open an issue if there is a problem.
This attitude is stupid and doesnt help the project.
