Public bug reported:
There's a display corruption (white pixels at random locations on both
screens connected to the iGPU that disappear in a second) that appears
when using 8 threads from 16 of my CPU (AMD 8700G with Radeon 780M).
I have two screens connected, one with HDMI and the other DP and the
corruption appears on both screens.
When the CPU is used at less than 50%, everything is fine.
