Myst Online: Uru Live currently does not exist, it was shut down (Cyan
announced to make it open-source within the next months though, so that it can
be played and tested again).
However, the problem is still present with wine 1.1.13 in Uru: Complete
Chronicles (or The Path of the Shell), which uses almost the same game engine.

This is printed constantly as the game runs:
fixme:d3d:apply_draw_buffer >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from
glDrawBuffer() @ context.c / 1450
fixme:d3d_surface:read_from_framebuffer_texture >>>>>>>>>>>>>>>>>
GL_INVALID_OPERATION (0x502) from glReadBuffer @ surface.c / 1003

And I get this error many times when it starts or loads a new age (as worlds
are called in this game):
fixme:d3d:IWineD3DDeviceImpl_EvictManagedResources (0xf56250) : stub

This appears one time as I start the game:
fixme:d3d_draw:drawPrimitive Using software emulation because not all material
properties could be tracked

And this also appears sometimes, I don't know exactly when:
fixme:d3d:state_vertexblend_w Vertex blending enabled, but not supported by
hardware

The high CPU load remains.

When I remove the OffscreenRenderingMode setting (it was set to "pbuffer"), the
"GL_INVALID_OPERATION" messages disappear, but the other messages and the CPU
load remain and I get graphics glitches in some of the ages.

The problem was present for all versions of wine I ever used to run Uru, which
is every version from June 2007 and later. I set the version to 0.9.40 because
that one was released on June 26th, 2007.
