Corrupt background and some corrupt icons [Intel Coffee Lake]

[Luca Palazzotto]

As soon as I upgraded to Ubuntu 20.04, two green pixel stripes appeared on my desktop.
They do not interfere with windows when opened, whether they are browsers, files or other items, and they do not seem to have an impact on the general behavior of the PC.

Still, something tells me that they are not supposed to be there.

I have a dual boot, Windows and Ubuntu, and two drivers:

VGA compatbile controller: Intel UHD Graphics 630 (mobile)
3D controller: NVIDIA GP107M [GeForce GTX 1050 Ti Mobile]

Any support would be welcome.

Thank you for your bug report, could you add a screenshot showing the issue and a 'journalctl -b 0' log after hitting the bug?

[Luca Palazzotto (lpalazzotto)]

Hi Seb,

Attached what my background looks like. Today it has been giving me other
problems too, like dark-purple screen.

I do not understand what you mean when you say "after hitting the bug".

Here is what I have when I launch 'journalctl -b 0'

$ journalctl -b 0

[Daniel van Vugt (vanvugt)]

Hard to say. You're already using the best graphics driver available.

Maybe the problem is a RAM defect? Try running a memory test from your BIOS. Or you can make a bootable USB stick:
