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.

Hello Paul-Antoine, With latest mesa release 17.3 is there any changes? Thank you.
Hello again, I tried to reproduce on a SKL with xcfe and debian sid up-to-date installed, xfc4-screenshot works fine, and I can't reproduce any hang or crash. kernel version : 4.14.0-1-amd64 Mesa driver : OpenGL version string: 3.0 Mesa 17.3.0 os version : Debian GNU/Linux unstable (sid) x86_64 kernel driver : i915 Xorg -version : 2:1.19.5-1 platform : Skylake motherboard model : Inspiron15-7568 cpu information : Intel(R) Core(TM) i7-6500U CPU @ 2.50GHz gpu card : Intel Corporation HD Graphics 520 (rev 07) (prog-if 00 [VGA controller])
Hello Elizabeth, Thank you for the update and for trying to reproduce the bug on your side. I don't have the incriminated config at hand for now. I'll let you know as soon as I get it back.
I'm unable to reproduce this issue on: Intel(R) Core(TM) i5-6440HQ CPU @ 2.60GHz Intel(R) HD Graphics 530 (Skylake GT2) (0x191b) Ubuntu 16.04 LTS (Kernel 4.4.0-109-generic) X.Org X Server 1.18.4 Mesa git master (4584c4ef049a) xfce4-screenshooter 1.8.2 Also tried Mesa 17.1.10 (834d6c60db26) and Mesa 17.3.1 (4f5e85e9e97d) with the same result. Only one strange thing found: when moving cursor slowly during area selection, all is fine. But when moving fast, some inputs are dropped and cursor becomes "detached" from the selected square. Moving again aligns selection to cursor. But anyway this not result in any error.
Tested again on Debian buster, can't reproduce. - Intel(R) Core(TM) i5-6440HQ CPU @ 2.60GHz - Intel(R) HD Graphics 530 (Skylake GT2) (0x191b) - Kernel 4.14.0-3-amd64 #1 SMP Debian 4.14.13-1 (2018-01-14) x86_64 GNU/Linux - Mesa 17.3.3 - xfce4 4.12.4 - libdrm 2.4.89-1 - xserver-xorg-core 2:1.19.6-1 - xf86-video-intel 2:2.99.917+git20171229-1 - xfce4-screenshooter 1.8.2-2
Sorry for the late reply. I am now using Mesa 17.3.3 and it works correctly again. Thanks for your help!
Awesome! Thanks for the update Paul.
