5.0 live usb screen tearing

Why does this happen?

Can you tell us the pc make and model as well as some hardware information; CPU, GPU, MOBO where you ran the Live USB?

And where I ran the live usb? I'm not sure what answer to give. I stuck it in the usb port and at boot selected the first option I think to start the live desktop.

lol fair enough. I meant, what hardware was Linux Lite Live USB running on, and yours by the way seems to be capable enough to have a smooth Live USB experience. Did you check the iso file? I see you're using Mint 19.3 so go here https://forums.linuxmint.com/viewtopic.php?t=301277 in case you don't know how to do that, once you do  or if you already do then go here https://www.freecinema2022.gq/download.php scroll down to where it reads Linux Lite 5.0 64bit - 1st June, 2020 and proceed to verify your .iso file

Yep, the md5sum and the sha256 keys match.

a smooth Live USB experience

Well sure it was smooth, the mouse wasn't laggy or torn like the rest of the screen. I even managed to click restart in the shutdown menu. Then it shut down without restarting.

[daniqwe]

So I found an article which could be the solution. https://learnubuntumate.weebly.com/scree...phics.html
Solution:
sudo mkdir -p /etc/X11/xorg.conf.d/
sudo nano /etc/X11/xorg.conf.d/20-radeon.conf
-insert:
Section "Device"
    Identifier "Radeon"
    Driver "radeon"
    Option "TearFree" "on"
    Option "DRI" "3" (add if other lines not enough)
    Option "AccelMethod" "glamor" (add if other lines not enough)
EndSection
-reboot system for the new configuration to take effect

But what do I do about it? The screen is worse than the article pic and I can barely see anything. Even if I somehow manage to follow the instructions it's still a bootable usb. Won't the changes revert after a restart?

Have you installed LL on your pc yet? Are you still running the Live version? whether you have or not: Don't do this!! I just checked your inxi output above and

Code:

driver: amdgpu,ati

this is the driver your pc's GPU is currently using, not radeon. There should be an amdgpu.conf file either at /etc/X11/xorg.conf.d or /usr/share/X11/xorg.conf.d/

[daniqwe]

Before I try installing it, I want to see if the live version runs fine at least. I tried xubuntu, LL... Devuan just straight up refuses connection to xorg server and I can only use the console.
The one that works fine & got installed is MX linux but it's not really my cup of tea. Some minor screen tearing still happens in games.
Even Mint mate/xfce has this same screen tearing. I mean it's Mint 20 instead of the 19 I had but the only difference is, it's based on Ubuntu 20.04 instead of 18.04. I'll try Mint 19 again and if it works, I'll just stick with it.

[daniqwe]

I guess Mint 19 stays.
