Bug ID: 91600 Summary: WoW crashes in OpenGL mode with Mesa, but not with NVIDIA blob Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: rankincj@googlemail.com QA Contact: dri-devel@lists.freedesktop.org
Created attachment 117619 --> https://bugs.freedesktop.org/attachment.cgi?id=117619&action=edit WINEDEBUG trace, including R600 shaders
Hardware tested: Linux x64, both HD4890 and HD6450
World of Warcraft (OpenGL mode) has been crashing ever since it upgraded itself to 6.2. I had assumed that it was a bug in the WoW client, until I noticed that WoW did not crash on a machine running with the NVIDIA binary blob.
I have executed WoW using the following command:
$ R600_DEBUG=fs,vs,gs,ps,cs WINEDEBUG=+opengl,+wgl,seh ./Wow-64.exe
And it appears that WoW is throwing an exception in a glLoadMatrix() operation:

I don't know how to debug this any further; the more flags I add to WINEDEBUG, the less likely WoW is to do *anything* (i.e. "run at all"). Raising this as a means of requesting more ideas.
