--- Comment #17 from Stefan Dösinger stefan@codeweavers.com --- One more thought - can you check the values of buffer_state->size? If they are not 256 byte aligned it might fail as well. My suspicion is that we're dealing with e.g. a 128 byte buffer (though 4096 byte are more common), which the driver might accept as "bind the whole buffer" but doesn't accept as "bind the first 128 byte of this buffer", even though it actually means the same.
