Flickering menu on 3D area only when using remote desktop

[cgltower]

Hi All
I have a 3D 32bit modelling program that uses directx9 and works in Wine on the server just fine. When I connect to the server with remote desktop client such as TurboVNC, or X2GO and run the program with VirtualGL (redirects display:0's GPU output to the remote desktop's screen) then there is a flicker of the 2D menus over their top and bottom position of the main 3D window. The 3D window itself shows ok.
I think its something to do with xcomposite or xdamage when connecting with remote desktop. As if the 3D updates are too often and overlaying the 2D menu. There is a test to use VirtualGL on the server alone and that shows the program running fine too, so I think its an issue with X, Wine and whatever remote desktop software I use.

Im curious if there's something simple I can try with Wine configuration - Ive tested the setup with these regedit changed:
HKCU>Software>Wine>Direct3D>
AlwaysOffScreen disabled
DirectDrawRenderer gdi | opengl
OffscreenRenderingMode fbo | backbuffer
RenderTargetLockMode disabled

and
HKCU>Software>Wine>X11 Driver
DesktopDoubleBuffered N

and
HKCU>Software>Wine>DIB Engine
Enable Y

... all in and out of a Wine emulated virtual desktop to see if playing with buffers/depth helps but to no effect.

Anything else to try before submitting issue to the other projects?

Thanks for any help

There have been some changes recently that might affect VirtualGL.
Try wine-1.5.10 and see if it's better (or worse).
