I don't know what video card you have, but you may want to try running
Diablo II in Glide mode, using the Glide-to-OpenGL wrapper:

Place the contents of the wrapper into the Diablo II folder. With Wine run the
"glide-init.exe" and you can try a test of the wrapper there. If all
is well, run the Diablo II Video Test and Glide mode should show up. Select it
and try running it that way.
I use this wrapper with an NVidia GEForce 9400 GT and it's flawless.
Good luck!
