After uninstalling nvidia driver see this thread: How to Uninstall (revert back to default driver) Nvidia Drivers?
whenever i on my PC and Login screen comes up, i can press the Num-lock and enter password normally, however if on login screen i let it be for a min and password field disappear and only time shows up and then if i press a key to enter my password (any key) to basically kind of wake the login screen. the screen flickers very intensively for a few second and then password field appear and it goes back to normally.
I am using SDDM and all theme shows this behaviour
i remember it didn’t happened before i installed and uninstalled NVIDIA drivers. i have tried to reapply the theme but it doesn’t fix the issue
i know it’s hard to explain and i tried to record it but my shitty mobile camera isn’t able to capture it.
