Using Linux

I first started using Linux in my second year of middle school so about 14 years old. I got introduced to the world of Linux by my teacher Renick Bell. I was having performance issues and he asked me if I wanted to try Linux. At that time, I had just started using computers so I was quite unfamiliar with Windows. So, I agreed to try dual booting Linux. He helped me install Manjaro Linux with the XFCE window manager. I started using it and I had no issues with Linux itself other than that I could not see my old files in Windows. Eventually, I felt that my computer was still slow and combined with the files issue, I just decided to use only Linux. In the end, it did not really improve my speeds but I got quite comfortable with Linux and used it with no issues. That was until I got a new laptop an ROG Strix. I did the same install on it. From the start, I had screen issues. Weird grey lines would appear on my screen. After trying to find a software issues, I concluded it might be a hardware problem. The repair shop confirmed that it was and I had to get it repaired 5 times before they just replaced it. Now, I do not that screen issues but I still had other screen issues. My screen would behave like an old CRT TV refreshing when I watched videos or scrolled. After much searching, I found a solution. I started using Picom with many flags. During this time I also switched over to the i3 Window Manager.
