xtrace of repeated CreateDrawable and DRI2-InvalidateBuffers events

During debugging of the issue reported in bug99333, I noticed that Plasmashell sends repeated CreateDrawable requests with same ID (with no DestroyDrawable in between).
I don't know if this is against specifications, but in any case the server should probably handle or reject it.

I have attached a cut from an xtrace.

The DRI2-InvalidateBuffers event is repeated the same number of times that the CreateDrawable has been received by the X server (I have seen more than 1000 repeated events while verifying the patch for bug 99333).

Apparently this issue was already reported several years ago.
