I have a problem about three days ago I installed fedora kde and the interface was normal but when I updated I had some problems with the interface, the background of the task manager was red, as well as in the customization part where the themes are
I already deleted the xdg and already updated the kernel to version 5.19 when the problem arose after updating but still the problem persists
Try changing the theme. I have not seen that, but also do not use KDE nor themes.
It’s the first thing I tried and nothing, I installed all the updates but it was still the same apart from that red background was in all the kde applications even if it’s in a part
