Strange graphical "glitch" at the bottom of display after some time using Manjaro KDE

First of all. Thank you for you time Manjaro community. English is not my first language, spanish is. Sorry about that. Please just watch this video i captured with OBS. Watch it at fullscreen to see that strange “mirror effect” bar at the bottom of my screen, you could clearly see that the cursor movement can be seen in the bar after moving it at the top of the screen. This glitch appears after some minutes or hours of using the desktop normally for some browser stuff and file management. I’m using KDE plasma. What can be happening here? Any ideas? D: PSDT: i can’t show the glitch with a screenshot because it does not show on it. weird. the best way is to show it from a video.

i think you should check this out
https://wiki.archlinux.org/index.php/NVIDIA#Installation

https://wiki.archlinux.org/index.php/Xorg#Driver_installation

its probably for drivers
its said that nvidia package only support 630-900 series
install the driver that support your video card and remove the others
