Hi,
Problem: I have been using (up-to-date) Leap 15.0 (Please note that I am virtually a novice Linux user). There is pseudo-random flickering on my screen, which gradually increases its frequency when the computer resources being used more. I am not able to read a single typical-size paragraph without encountering a flickering.
There seems to be similar threads regarding the same/similar issue, for example:
https://forums.opensuse.org/showthread.php/532809-Monitor-flicker-or-dropouts
https://forums.opensuse.org/showthread.php/527062-KDE-Plasma-desktop-5-flickering-screen
I have amateurishly tried some of the solutions suggested thereat. Nevertheless, the flickering issue persists.
Some information about the workstation is as follows:
