Subject: radeon/dri2: if the depth buffer is 16-bit force cpp == 2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d81a48757a9bde35299fd7c3cfbe83885238409a;p=mesa.git

radeon/dri2: if the depth buffer is 16-bit force cpp == 2

This is because the DDX always allocates using the drawable sizes.
which gives me twice the depth buffer I asked for, dumb.
