When I draw an object in wireframe as triangle strips with drawelements function, degenerate tris shows up as lines… Is this a driver bug?

Sounds normal to me. The triangle is degenerate, so it won’t get rendered if your polygon mode is GL_FILL. However, (two of) its edges are not degenerate, so they remain visible in GL_LINE mode.
