           Summary: crash in CompressedTexSubImage2D on Intel since
                    wine-1.1.27
           Product: Wine
           Version: 1.1.27
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: hoehle at users.sourceforge.net


To fix bug #19412 (on Mac with NVidia), Henri Verbeet committed the following
patch to wine-1.1.27 which unfortunately causes Colin McRae 2.0 (incl. demo) to
crash on Linux with Intel graphics.

commit b7812932bc74cf4411bfdbb2277fb0aaf8e24b04
    Passing NULL to glCompressedTexImage2DARB() doesn't work particularly well
    when both client storage and PBOs are enabled. Also, two years is long
enough
    to give driver developers a chance to fix the bug this was supposed to work
    around.
-        /* glCompressedTexImage2D does not accept NULL pointers, so we cannot
allocate a compressed texture without uploading data */

To get CMR2 to run with Intel graphics, you need to activate s3tc via the
~/.drirc file. Then, OpenGL will report support for texture compression (see
bug #15636, comment #7), which CMR2/Wine needs for DXTn formats.

I'm using Ubuntu Intrepid with Intel i915. It's strange that something that
originated as an Apple issue now affects Linux.
