Graphic artifacts with Ryzen 5 2400G

[johnb]

First of all, I'm very new so I apologize in advance for any mistakes, overlooks, etc.

I flashed Kali Live 2020 to an USB flash drive using three different methods, all three yielded the same result. The latest one was using Rufus 3.7, adding a persistent partition.
When I start Kali for the first time, everything works as far as I can tell. Second time I start, a green screen appears after the logo. If I leave it enough time (till the screen goes off) the login screen eventually appears.
Then, it works very slow and with graphical glitches. I tried to capture screenshots but they come out fine, so I took a pic with my phone.

I also tried using balenaEtcher and manually creating the persistence partition, same thing happens, as well as using MiniTool Partition Wizard (I have a Windows 10 system). I used different media and it didn't change anything.
This doesn't happen if I don't create a persistence partition.
I also updated my BIOS (Gigabyte AB350N) to the latest version, same results.
I also tried installing amdgpu-pro but wasn't able to.

Any help would be appreciated!

hey, im not a pro with this stuff. i tried to install kali on my amd ryzen3 2200g and im facing the same problem.ive tried installing 2 times. it loads fine for the first time but at the second time after entering username and password the screen goes green.
you must try doing sudo apt-get update and sudo apt-get upgrade on the terminal. you can go to the terminal from the username and psswd screen by pressing CTRL + ALT + F4.
ive tried this but i couldnt complete cus of my broke internet .
give it a shot. i dont really know whether it will work or not and i also think this can be an issue of APU.
thanks

i am using ryzen 7 4800hs using the new renoir (amdgpu) graphics driver.
i do get residual artifacts like these.
what solved for me was changing the resolution and refresh rate in X.

my hardware outputs on eDP and the LCD has a refresh rate of 144hz so for me it was

xrandr --output eDP --mode 1920x1080 --rate 60
xrandr --output eDP --mode 1920x1080 --rate 144

to check yours.

xrandr

look for the output, mode and rate supported.

hope it helps.
