[Bug 32273] New: Might and Magic Heroes VI displays character polygons poorly.

http://bugs.winehq.org/show_bug.cgi?id=32273

Bug #: 32273
           Summary: Might and Magic Heroes VI displays character polygons
                    poorly.
           Product: Wine
           Version: 1.5.17
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Might and Magic Heroes VI displays the character polygons poorly. This hinders
gameplay, because you see only part of your characters on the map or on the
battlefield. A screenshot of the paladin character in the main menu is attached
as an example.

This looks similar to a wine bug for The Witcher, see
http://bugs.winehq.org/show_bug.cgi?id=12771#c18 and comment 19, the screenshot
attached by Kevin Meyer. This does not seem to be a duplicate however, as the
original bug describes a bunch of graphic issues specific to The Witcher.

This is still a bug in wine 1.7.2. The bug happens occasionally and randomly :
sometimes the polygons will appear properly and other times they appear like
the screenshot I uploaded. The log for both good and bad cases is identical, so
it's hard to tell what causes this bug.

Xavier, good day to you!

I've seen this bug (at least one which visually looks just the same) on my
system when been playing King'd Bounty: The Legend and even had been trying to
debug it. What I had tried to do is to capture GL command stream using apitrace
for the case when I hit the bug and for the case when I don't. Trouble was that
actually it turned out to more likely be a bug in nVIDIA drivers as absolutelly
the same trace had been producing both bugged and non bugged rended depending
on something I hadn't been able to figure out. I had reported this bug to
nVIDIA (made a post to the forum they had been using as an "Official nVIDIA
unix support forum" a year or two ago) but it seems that this report didn't
attract any attention from nVIDIA devs.

UI tried Might and Magic Heroes VI and Witcher and it seems that this are
different bugs.

Please re-test in light of changes at #34052. It seems that this has been
prevented from occurring at least some of the time.

I've tried to run the game in VM Ware and got the same results. So it seems to
be drivers issue. 
However, when I try to run the game using integrated Intel video, I see only
garbage on the screen.

Here's a workaround for the missing polygons bug in King's Bounty: The Legend -

Open up regedit:

Go In HKEY > Current User > Software > Wine > Direct3D
Create a new String Value with the name "MaxShaderModelVS" and a value of "0"

The game should now display character polygons properly.

Tested on:

Linux Mint 17.3
Nvidia Geforce GTX 960 with proprietary drivers 355.11
Wine 1.8 + CSMT (64bit prefix)

Haven't tested any other King's Bounty games.
