If that was missed, the compositor would be rendering the new size but only the original size would be shown - that would be easy to see. dri3_get_buffer() would be the right spot to add printfs to see what was going on. Compiling xf86-video-intel with ./configure --enable-debug=full would generate a huge Xorg.log from which we can check what size of pixmap is being rendered. But again not why.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
