neither, nor.

either the slowness is unrelated to this item (you'll then have to figure
whether maybe some effect causes this, try blurring, and file a bug on it) or
you have to set the scale method to "smooth" rather than "accurate" (which is
the lanczos filter, TLF has been removed for triggering crashes on at least at
chips and not being a real advance anyway)

the lanczos filter (only used during some scaling effects like present windows)
uses some caching now and thus should be "fast enough" (and apparently is on
ati & nvidia chips) but if it's still just too slow on a majority of intel
chips, we may have to rethink the (unconditional) default setting.
