[snb] GPU HANG: ecode 6:1:85fffffc, in Renderer
I'm a hobbyist. Please be nice.
Occasionally, I'll see diagonal random squiggly lines, as though the desktop failed to refresh properly. One time after it happened, I looked in the kernel log. I happened to see this notification of a GPU hang in my kernel log, and the nice friendly note asked me to file a bug report here. Hopefully I've provided enough information in the rest of this report for you developer folk to work with.

Here's the relevant part of the kernel log, with a line or two extra at the top and bottom:

11/26/20 10:54 AM GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
11/26/20 10:54 AM Please file a _new_ bug report at https://gitlab.freedesktop.org/drm/intel/issues/new.
11/26/20 10:54 AM Please see https /gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs for details.
11/26/20 10:54 AM drm/i915 developers can then reassign to the right component if it's not a kernel issue.
11/26/20 10:54 AM The GPU crash dump is required to analyze GPU hangs, so please always attach it.
