Horizontal sparks on the screen, caused by driver or a electrical fault?

[Aknot]

I have some weird horizontal "noise" flickering on the screen, almost like sparks, can this be caused by the graphics driver? Best seen in the lower right corner.

The VGA adapter is a AMD Radeon and I have tried TearFree true.

Radeon.conf is set to modesetting on pci0:1:5:0.

Thanks,

Can't tell for sure, but wouldn't be surprised if it was the cable.

...wouldn't be surprised if it was the cable...

I actually read that this was common, but these sparks doesn't change at all, when moving the lid back and forth.
I have cleaned the connector with alcohol and a cotton swab too, just to be sure, no difference.

Tap and press at that spot to see if they change at all. If they do, it's the display.

Historically those types of glitches are more often caused by driver/os issues.
