Dont precalculate mask in loop body

No need since we dont shift. Avoids the extra mask instructions for the
not found case.

Apparently it needed some kind of GTK desktop portal or the other

Interesting that its numbers are basically the same as alacritty's. Lot
better than I remember, I guess the recent libvte performance work was
good.
