All the rendering is done as a XCopyArea from a ShmPixmap which basically results in manual detiling through WC mmap.

I think either of them will fix the kdm corruption, so they require a little soak testing (pretty much try and reproduce the earlier swapping -> corruption issue).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
