I installed Manjaro on my PC and it keeps showing flaws on the display

hello everyone, i have a big problem. I am new to the linux world and i have no experience with it, but as a result of some recommendations, I felt persuaded to join the Linux Manjaro family. But after installing version 21.0.2, I came across many flaws in the display of the Manjaro environment. Please help me to solve this problem, and stop all the glitching, because I am a very layman when it comes to linux OS. Thank’s.

Welcome to the forum! Please read the informative post linked below.

Thank’s for the reply, i was thinking it would take at least a week to get a response.

What should i do to get this information in Manjaro?

I think is this what you mean.
