sorry if i posted this in the wrong place as it is my first time on this forum, and my english is not very good as i use translator.
I currently use Ubuntu 20.10 and I decided to install MATE on it, when I switch to the MATE desktop the screen looks very choppy, I thought it was Ubuntu's error and I decided to try Ubuntu MATE and installing it brought me the same surprise, before I tried ubuntu mate 18.04 lts and it worked perfect for me, but with the most recent version no longer, and I don't think it's a problem with ubuntu MATE but with the desktop, I use the HP 245 G6 Laptop (amd).

Again I apologize if I made a mistake about something.
Thanks
