          Priority: P2

Hi there,

this is a regression introduces between wine-1.1.3 and wine-1.1.4

It affects Morrowind version 1.2.0722, when OffscreenRenderingMode is set to
fbo. GLSL settings don't seem to have any effect on the issue.

Console output doesn't seem to be related to the problem. I get a lot of those
though on my Nvidia NV35:
fixme:d3d_shader:shader_glsl_deselect_depth_blt >>>>>>>>>>>>>>>>>
GL_INVALID_OPERATION (0x502) from glUseProgramObjectARB @ glsl_shader.c / 3450

I'm currently bisecting and these msgs also appear when the state is good, so
they're probably not really related.

How does the issue look like:
The Waterplane (pixel shader water is on) and the sprites flicker a lot when
moving through the terrain. Sprites also does include parts of the trees and
e.g. lillies in the various pools outside of Seyda Neen.

Interesting observation:
When pressing ESC, which does bring up the ingame menu (Save, Load, Exit - you
get the idea) the graphics are perfect. Always.

Posting bisect info later.

Greets,
Tobias
