Hi,
I have an issue where st_TexSubImage causes very high CPU load in __memcpy_sse2_unaligned (Mesa 10.1.3, Xorg 1.15.1, radeon driver, HD 7870).
Any obvious causes / tips for this? e.g. align textures or use different format/type? I 've tried using GL_BGRA/GL_UNSIGNED_BYTE and GL_BGRA/GL_UNSIGNED_INT_8_8_8_8_REV
