After a bit more checking it's not so much a bug as it is a result of opengl
point size limitations. The game sends point sizes per-vertex, which wine does
not support as the only explicit way to change point sizes is with
glPointSize(), which is global.

I managed to get somewhat proper smoke and fire effects by forcing point size
to 64, then enabling GL_VERTEX_PROGRAM_POINT_SIZE and setting appropriate
attenuation. This way, point size is always high when close, and falls off
slowly.

There has to be a better way of doing this - my way butchers normal point
processing and only works because sh3 scales them similar to this way anyway.
Is there any other way to render these? Maybe convert to billboards?
