  • I have this problem on my laptop HP Elitebook 820 g1. It's actual only for Ubuntu and not for Windows. It shows unpredictably and sometime pass away by itself. Now I cure it with screen blocking, and after reauthorization artefacts vanishes for a few minutes.

    There is Intel i5-4200u inside. And it has built-in Intel HD4400 graphics.

    Here is hwinfo:

    And glxinfo:
