So si_texture_transfer_map may allocate a new buffer of the original bo_size, which is smaller than the combined size of the resources => its CPU mapping doesn't always cover the calculated address. This quick'n'dirty patch prevents the crash, but now totem just hangs for me.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
