--- Comment #11 from Roland Scheidegger sroland@vmware.com --- Created attachment 137762 --> https://bugs.freedesktop.org/attachment.cgi?id=137762&action=edit copy over export color mask
Would this patch help? I think the r600 code forgot to copy over the export mask (at least the eg code does it).
