SUMMARY
***
1. After fresh install of Fedora Linux with kde plasma on my optimus laptop,
followed the official instructions to install NVIDIA proprietary drivers from
here -
"https://docs.fedoraproject.org/en-US/quick-docs/how-to-set-nvidia-as-primary-gpu-on-optimus-based-laptops/";
2. After rebooting clicked on the session selector in bottom left side of sddm
like between 'Plasma (X11)' or 'Plasma (Wayland)', and the drop down menu of
session spawned in top left corner of the screen.
3. Noticed whitish screen flickering immediately after clicking and as soon as
clicked somewhere else it goes back to normal.

3. Noticed whitish screen flickering immediately after clicking
OBSERVED RESULT
White screen flickering continuously, didn't stop until i clicked somewhere
else on the screen, after clicking again the flickering stops.
