So this means that we're looking for some sort of inconsistency between NVQueryImageAttributes and how far into the source buffer NVPutImage reads. Sadly the logic in NVPutImage is separate, and is much more complex. By the way, it occurs to me that I didn't mention what hardware I'm using, in case it matters: 02:00.0 VGA compatible controller: NVIDIA Corporation G96 [GeForce 9500 GT] (rev a1) And I'm using x11-libs/libdrm-2.4.40 (which nouveau_xv.c depends on via nouveau_bo_*)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
