I’m not sure the following solution matches with your issue (yours could be related to GPU drivers, I see), but recently we had an issue occurring on most of the KDE implementations.
By-the-way, we would need your garuda-inxi, as requested by the template.
If you don’t have a KDE edition, or anyway the solution above does not work for you, maybe the best thing would be restoring the latest working snapshot, provide the garuda-inxi, and describe better what you did when the issue occurred.
