I see this is removed instead of moving after blacklist.


Is this what you want?

[ajuma, 2014/04/17 22:57:17]

Since we're already returning true after the blacklist check, checking this
condition after the blacklist check doesn't change the return value (we return
true either way).

The only difference is for a system that's blacklisted, you can use
--enable-bleeding-edge-rendering-fast-paths to turn the feature one.  Now you
can't.  But it's your call, as you can still turn it one with
--enable-gpu-rasterization.
