Only a cursor was visible. The cause is +"Make PixmapDirtyUpdateRec::src a DrawablePtr" in xserver, the "src" +pointer might point to the root window (created by the server) instead +of a pixmap (as created by xf86-video-intel). Use get_drawable_pixmap to +handle both cases. + +When built with -fsanitize=address, the following test will trigger a +heap-buffer-overflow error due to to_sna_from_pixmap receiving a window +instead of a pixmap. + +Test on a hybrid graphics laptop (Intel + modesetting/nouveau): + + xrandr --setprovideroutputsource modesetting Intel + xrandr --output DP-1-1 --mode 2560x1440 # should not crash + glxgears # should display gears on both screens + +Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=100086 +Signed-off-by: Peter Wu <peter@lekensteyn.nl> +--- +Tested with xserver 1.20.1 with ASAN enabled.
