Not at all, those are very common. And harmless.

Not a bug. I figure something changed and you hit now a different code
path that sets the D3DUSAGE_WRITEONLY flag. That's just a hint to the
driver that the application doesn't intend to read that VBO or index
buffer. The driver is free to take that hint or ignore it.
