Oh neat. I was seeing that render blue as well, but was assuming it was due to
some spill errors that I had only semi-fixed.
The interesting thing to note is that the commit in question doesn't actually
enable ARB_texture_view on any driver, just sets the stage for it.
My guess is that it's due to the st_format.c hunk, but I can't imagine why. Oh
hrm. Perhaps this hunk, I can't remember what that did, but it seems
potentially dodgy:

+ else

src_format = util_format_luminance_to_red(src_format);
src_format = util_format_intensity_to_red(src_format);
