Subject: set miptree pitch to region pitch after allocating the region in st_miptree_create()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7966e479dca22bf2d2b844d50ac5bef70614e15a;p=mesa.git

set miptree pitch to region pitch after allocating the region in st_miptree_create()

This fixes rendering with small (4x4) textures with softpipe.
Haven't yet tested with i915.
