What's your Cairo version? The input focus rectangle has been identified as a performance problem some time ago: http://lists.freedesktop.org/archives/cairo/2006-October/008135.html "Another thing we identified at GUADEC is that the dashed stroke for the focus rectangle that GTK+ uses is also a performance problem. This is another case that we should ensure is going through the fast path for whole-pixel regions." though I *think* it has been adressed since. But if you are running 1.4, that would hint that it still is a problem. P.S. The performance-list[1] might be a better place for this discussion...
