resource_check_usage Unhandled usage flags 0x8

[Luis C. Busquets Pérez]

I do not from which exact version of wine, whenever I run Civilization
IV bryond the sword, losts of fixmes appear with the message

fixme:d3d:resource_check_usage Unhandled usage flags 0x8.

Since those fixmes did not appear before I wonder if this is a bug.

I do not understand how it is that the function resource_check_usage
uses a flag that before it wasn't, was it? Can anybody clarify the usage
of the flag 0x8 and if this is a bug?

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.
