Wine rendering issue - white shiny spots all over trees

[ypeace11]

I have a Windows application that is rendering a green playground/park like area. There are white shiny spots rendering leaves on the trees. I would like some help to overcome this issue. At least if some one can help me what is causing this, I can get hold of the windows developer and work around this (if possible!)

Wine version: 1.7.17 (& wine 1.6 stable)
Ubuntu 13.10 (also on 12.04)
Virtual GL : 2.3.3
nVidia K520 - 331.79 (latest)

The tree rendering images are here.

Wine log is posted here:

To overcome this, I tried the following (but found no use)
1) Wine3d registry settings to use: backbuffer, pbuffer etc
2) Wine desktop without virtualgl
3) winetricks install d3dx9

Based on some of the forum answers - this is a directx-opengl texture rendering issue (and precision issues relating to rendering) .
Could some one comment on this ?
What exactly should I convey to the Windows developer to avoid this kind of rendering.

Thanks a lot

The rendering of the trees has washed out appearance than random white spots.

Nothing. If there's something broken in Wine, it should be corrected in Wine.
The job of your windows developers is to make sure that their app is not broken and runs fine under Windows.
They should not be concerned at all with Wine.
The job of Wine is to make your windows application run as much as possible like it does on Windows (which means that if it is broken under Windows, it'll be broken under Wine).

You should first make sure that the issue is absent under Windows (you didn't say if it was).
If it is indeed the case, then it may be an issue with Wine that can be investigated here.

Thanks for your reply. I agree Wine should work like Windows.

To clarify the issue:

It is not broken under Windows. I want the Wine rendering to look like that of Windows.
The Wine rendering looks washed out when compared the corresponding Windows rendering.

Retest in 1.7.20 and if the problem persists, file a bug.
