            Bug ID: 103447
           Summary: [SKL] GPU hang when using xfce4-screenshooter
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: listes at defendingthemusic.fr
        QA Contact: intel-gfx-bugs at lists.freedesktop.org

Bug description:
When I use XFCE screenshooter to select a screen area to capture, the whole GUI
freezes (except the mouse that continues to move but click is inoperative) and
X restarts.
The relevant diagnostic from dmesg is:
[drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [1092], reason: Hang on rcs0,
action: reset

System environment:
-- chipset (`lspci -v`): 00:02.0 VGA compatible controller: Intel Corporation
HD Graphics 530 (rev 06) (prog-if 00 [VGA controller])
-- system architecture: x86_64
-- xf86-video-intel: xserver-xorg-video-intel: 2:2.99.917+git20161206-1
-- xserver: xserver-xorg-core: 2:1.19.5-1
-- mesa: 17.2.2-1
-- libdrm: 2.4.84-2
-- kernel: 4.13.0-1-amd64
-- Linux distribution: Debian Buster
-- Machine or mobo model: Dell Precision 7710

Reproducing steps:
Open xfce4-shooter, in "Region to capture" choose "Select a region", then click
OK. The cursor turns into a small cross that can be dragged and dropped. Doing
so will freeze the whole X session.
