A lot of people have old drivers, you have to handle it.
Was that addressed to me? I didn't suggest otherwise. I simply answered the question about what was causing it. All the evidence indicates that changes to drivers have caused it.
Definatly not a driver issue, not for every instance anyway. Many new cards with new drivers have issues when you use this flag in your blitz programs.. obviously nothing to be done for it directly.
That doesn't mean it's not a driver issue. It just means it's a driver issue you have live with.
Could you tell me if anyone get an absurd slowdown
with this code (w/wo 256) or if anyone by any reason
get nothing written to the texture???

Approximately 1200 FPS ( with flip false ) with flag 256
Approximately 850 FPS ( with flip false ) without flag 256
Radeon 9700 Pro and recent-ish drivers.
Both ways I see rects being drawn to the texture.
