I followed the dri2 discussion on dri-devel
(http://www.mail-archive.com/dri-devel@lists.sourceforge.net/msg35990.html),
current dri2 implementation depends on glViewport being called whenever the
window/framebuffer is resized, otherwise renderbuffer can't be updated. In i915
dri driver, we first set functions->Viewport to intel_viewport, then this
function pointer is overrided by intelViewport, who calls intelCalcViewport and
doesn't update renderbuffer.
With this patch, we can resize glxgears as normal.
This patch also fix a metacity-clutter/DRI2 issue, that we only have
640x480 preallocated renderbuffer at metacity-clutter start and then the
buffers can't be updated anymore.
Please review and your comments are welcome. Thanks
Peng
