This is more of a technical support issue that should be discussed
on the Mesa and/or DRI development mailing lists than a bug. Once
you have discussed the problem on Mesa/DRI development mailing lists,
if the developers consider it a bug, please file a bug report in
the "xorg" bug tracker or Mesa bug trackers appropriately. When
you've filed your bug report in the upstream bug tracker, paste
the URL here and we will track the issue.
I believe you will find however that this is a configuration issue
rather than a bug.
Setting status to "NEEDINFO" pending status update of dri/mesa
mailing list discussion, and upstream bug report URL if determined
to be a legitimate bug by upstream developers.
I've since found out that this problem exists in drivers for 'other'
operating systems, so I no longer believe it is worth pursuing.
Please set bug status appropriately.
