Thanks to James Mckenzie and Austin English for earlier hints. I've installed more stuff (ubuntu packages) and spent a bit more time with d3d8.
I assume most people get these tests to work, so I'm a bit distressed I cannot seem to get them to work properly, 100%. The large amount of test code that 'just works' is impressive. I'd be reassured I was not breaking things in any patch I submit if I could figure out why I'm not getting 100% (that is, what the heck might I be doing wrong?).
Any hints/suggestions would be welcome.
In dlls/d3d8/tests/visual.c one has the call that gets errors:
1357 if (caps.VertexShaderVersion >= D3DVS_VERSION(1, 1)) 1358 { 1359 test_rcp_rsq(device_ptr); 1360 }
and test_rcp_rsq() does some *VertexShade calls not made elsewhere.
The last few lines of 'make test' output in d3d8/tests are:
fixme:d3d:WineD3D_ChoosePixelFormat Add OpenGL context recreation support to SetDepthStencilSurface fixme:d3d_draw:drawPrimitive Using software emulation because manual fog coordinates are provided visual.c:598: Test failed: Color components differ: c1 = 80, c2 = 00, c3 = 80 visual.c:632: Test failed: Color components differ: c1 = 80, c2 = 00, c3 = 80 visual.c:634: Test failed: Color component value is 80 make: *** [visual.ok] Error 3
These failures are in test_rcp_rsq(), the function called at line 1359.
Note that other calls to to getPixelColor() (a function in the test code, tests/visual.c) work fine. Only when a couple of special Shaders are invoked does getPixelColor() get something the test does not expect.
Possibly IDirect3DDevice8_CreateVertexShader() is not setting things up right or somehow the 'DRI' code in package libgl1-mesa-dri is not being effective?
I stuck a couple sleep(5) calls in the test source (to slow things down at the error points) and I can see the shader code has an effect visually (the test code generates small-ish windows with color blocks).
Compiling d3d8 and its test code -g (that is, no -O2) gets exactly the same results.

The 'libgl1-mesa-swx11*' packages are not installed, swx11 seems to be incompatible with some of the mesa stuff above (according to synaptic package manager).
Any hints/suggestions would be welcome.
