           Summary: Strange polygon in Wine 1.3.27 but not in Wine 1.3.0
           Product: Wine
           Version: 1.3.27
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org

I played the game PAL4 (仙剑奇侠传4. See http://chinesepaladin.org/tag/pal4 and
http://www.gamersky.com/Soft/200708/9540.shtml for description of the game)
under Wine 1.3.27 and Wine 1.3.0 and I discovered the following problem:

1. My laptop is Intel i915 graphic card with intel-dri 7.11-2 and
xf86-video-intel 2.15.0-2 driver.  I have tried playing the game with NVideo
driver and Wine 1.3.27 has no strange polygon problem.  So I suspect the bug is
Intel i915 graphic card related!

2. Under Wine 1.3.0, there is no strange polygon display problem.  See
wine-1.3.0.png in the wine-bug-report.7z.  The log file is attached as
wine-bug-report.cmp in the 7zip archive.

3. Under Wine 1.3.27 (even earlier versions such as 1.3.23 if I am not
mistaken), strange polygon display problem occur.  See wine-1.3.27a.png (S3TC
disable) and wine-1.3.27b.png (S3TC enable with driconf) in the
wine-bug-report.7z.  The log file is attached as wine-bug-report.log in the
7zip archive.

Details about my laptop:

1. Running the software:

    cd ~/.wine/drive_c/SoftStar/PAL4
    LC_ALL=zh_CN.GBK wine PAL4.exe -opengl

2. My distro is ArchLinux 32 bit and 64 bit:

Intel(R) Core(TM) i5 CPU M 430 @ 2.27GHz GenuineIntel GNU/Linux

3. The gcc version is
