This video link shows the bug I encountered.

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.

STEPS TO REPRODUCE
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 click on the session selector in bottom left side of sddm
like between 'Plasma (X11)' or 'Plasma (Wayland)'.
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.

EXPECTED RESULT
Should show the drop-down menus of session and language selector normally
without whitish flickering and without spawning the drop-down menu in top left
corner.
