/sys/class/drm/card0/error

I got this crash while restoring a minimized window in KDE Plasma (the screen
froze when the window was half-way in the process of being "zoomed", partially
transparent).

I am using kernel 4.12 since some days, I never got this problem with the
previous kernel 4.11. Kernel and xorg are from Fedora 25:

kernel-4.12.8-200.fc25.x86_64
xorg-x11-server-Xorg-1.19.3-1.fc25.x86_64

Here is the dmesg excerpt. Attached you may find the (gzipped)
/sys/class/drm/card0/error file.

Hang on rcs, action: reset
[115531.801823] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[115531.801824] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[115531.801826] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[115531.801827] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
