This is correct. Note that on master this was introduced by commit 7e61b44dcd6175579f60d8ff2f703a6c83e33d27 (mesa: enable GL_TEXTURE_LOD_BIAS set/get) and immediately fixed by the next commit bba8f10598866776ae198b363b3752c2e3bbb126 (mesa: Use IROUND instead of roundf). But only the first commit was cherry-picked to the 10.0 branch likely because the second lacked the CC to stable.
