I think that means that sna_pixmap_get_buffer() is NULL, if so the full debug log will just explode as well. Quite possibly that it is NULL after a composite redirect - I will have to think about that. If you apply diff --git a/src/sna/sna_dri2.c b/src/sna/sna_dri2.c index fd3edcc..1c26131 100644 --- a/src/sna/sna_dri2.c +++ b/src/sna/sna_dri2.c @@ -150,6 +150,8 @@ sna_dri2_get_back(struct sna *sna, int flags; bool reuse; + assert(sna_pixmap_get_buffer(get_drawable_pixmap(draw))); + DBG(("%s: draw size=%dx%d, buffer size=%dx%d, is-scanout? %d, pitch=%d, front pitch=%d\n", __FUNCTION__, draw->width, draw->height, get_private(back)->size & 0xffff, get_private(back)->size >> 16, and compile with --enable-debug (no need for =full, we just want to enable the assertions), that will confirm the theory.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
