            Bug ID: 88968
           Summary: Unit mouseover in World of Warcraft (wine, D3D)
                    freezes up the entire system
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: rubykuby at gmail.com

I'm not sure if I selected all the right bug tracker things, or whether this is
a Mesa or X11 bug.

I have an AMD Radeon HD 7950, which is practically identical to the R9 280.
When running World of Warcraft in wine, everything works fine until I mouseover
a unit. This mouseover should trigger a glow effect around the unit, but
instead freezes up the entire system, forcing me to reboot.

This bug does not occur in standard Ubuntu 14.10. It does occur in Ubuntu 14.10
with the oibaf/graphics-drivers PPA added. It also occurs in Manjaro 0.9.

Ubuntu 14.10 versions:
libgl1-mesa-glx - 10.3.0-0ubuntu3
xserver-xorg-video-ati - 1:7.4.0-2ubuntu2

Oibaf versions:
mesa - 10.5~git1502040730.6fd4a6~gd~u 
xserver-xorg-video-ati - 1:7.5.99+git1501140731.c80ea1~gd~u

Manjaro 0.9 versions:
mesa - 10.4.3-1
xf86-video-ati - 1:7.5.0-1

This bug does not occur when turning on the OpenGL mode within WoW. This bug
does not occur in the Catalyst drivers.

I do not know how to gather debug information, but I'd be glad to provide them
if given instructions.
