Issue occurred again after BIOS update, during make -j12. I also had
chrome and vmplayer running. Dmesg errors from journalctl:
kernel: pcieport :00:1b.0: AER: Multiple Corrected error received:
:01:00.0
kernel: pcieport :00:1b.0: AER: PCIe Bus Error: severity=Corrected,
type=Data
Public bug reported:
Running up-to-date Ubuntu-18.04.3 with kernel 5.3.0-26 on a Dell
Optiplex 7060 with an i7-8700 CPU and Intel UHD Graphics 630 (Coffeelake
3x8 GT2).
I had chrome, slack and vmware-player running in Gnome. While doing some
git clone, screen+mouse+keyboard froze for 2 minutes
One important detail: I also had an AMD radeon video card plugged in but
the display was connected to the integrated VGA port. After removing the
radeon card, the artefacts went away.

installation from an older Dell Optiplex (Ivy Bridge i7) to another
Optiplex with a Skylake i7-6700 CPU.
