I'm not sure the actual drawing is slowest, it's not showing up big time in the profiles. Things like singleWidth() are. I'm not really sure how I'd implement what you're suggesting anyway. We already have inset->width() ... And I seriously doubt I have enough understanding to do it. I have never worked out what the hell Inset::scroll() does, for example. Or the exact semantics of InsetCollapsable::need_update. john
