Every time I log in, there’s a graphical glitch that lasts about one second just before the KDE startup animation begins. This happens not only during system startup but also when switching users or logging in at any other time. I first noticed this issue on Fedora 41, and it has persisted after updating to Fedora 42. I’m using an NVIDIA GeForce GTX 1070, in case that’s relevant. If anyone has any ideas about what might be causing this or how to fix it, I’d really appreciate the help.
I have the same issue with NVIDIA GTX 1070 ti and sometimes in my case it seems that the video card outputs fragments of the last frame displayed in the previous boot in addition to the glitch
