Bug ID: 91765
Summary: SIGSEGV gpu_bo_download
Product: xorg
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/intel
Assignee: chris at chris-wilson.co.uk
Reporter: andreas.reis at gmail.com
QA Contact: intel-gfx-bugs at lists.freedesktop.org
On Haswell 4770, drm-intel-nightly, xserver-git & xf86-video-intel-git (at
sna/dri2: Stop trying to attach vblank events to pixmaps). Same setup as in bug
91467.
Was watching a video with mpv on fullscreen (opengl output driver for h.264
10-bit, so afaik no hwdec) and got a message notification (using dunst,
http://knopwob.org/dunst/index.html ). That caused rapid screen flicking with
the crash after a few seconds.
