The commit turned off the decompression with a blit for software rasterizers, so we're hitting a code path we never used for years. I think this uncovers an existing old bug instead of introducing a new one. mesa: fc25956badb8e1932cc19d8c97b4be16e92dfc65 (master 10.2.0-devel) getteximage-targets S3TC 2D_ARRAY passes on swrast now. |

Now Gallium drivers have the ability to turn them off.
