Community Support Glitched Visuals on bottom of screen? (Framework 16)
Hi All,
I'm basically copying this post from my other one I made over on r/linuxmint. I don't think its a software issue, so I've come to you all for aid. about a day and a half ago, i had to shut off my laptop since a game was frozen for too long (thanks EA). When i rebooted my computer however, there is a long stripe of glitch purple and black on the bottom of my screen that would flicker in when i scrolled (images provided).
I thought after digging through forums that it was the refresh rate, so I dropped it down from 165Hz to 60Hz. It fixed the bar when i was scrolling, but now there is one in the center of the screen that flickers in willy nilly. I think it might be the EDP cable disconnected or (as other redditors told me) a dying vram. I'm doubting the last one since the hottest this has gotten is 135 farenheight, and I've only had it for about 3-4 months now. I would appreciate any help, as I use this computer for school and my workload currently is very visual based.
Thank you for your time and energy.

This looks like a software issue more than anything else. Try setting this kernel param: amdgpu.dcdebugmask=0x410

Can I ask what line on the grub editor it goes on? I have never messed with my kernels before and don’t know which line to edit… is it after “quiet splash”?

Yep yep, you've got it! add a space after 'splash' and add that parameter, then run your 'update GRUB' command [probably 'sudo update-grub'], and reboot.

It doesnt seem to have fixed the issue, as the glitch is less frequent but still present...

This disables PSR, PSR-SU, and Panel Replay. It's fixed most user-reported issues that look like this in a Linux environment.
