<pre>Hi,
I have been using pretty much all mainline Linux kernel versions for several
years and most of them were OK with respect to my SandyBridge CPU/GPU, up to
and including 4.15.x kernels.
However, with 4.16.x kernels and 4.17 kernel, I see graphic corruptions. In
addition:
- with 4.16.x kernels my machine ended up freezing completely
- with 4.17 kernel I saw a GPU hang which I am reporting now
Here is more info:
- To reproduce this bug: use Plasma desktop for a few hours or days. It
starts with small graphic corruptions that amplify over time (see screenshots
below) and
it ends up either with a freeze or with a GPU hang.
