This check is incorrect because both values are quint8, which is unsigned it, therefore the condition is always true, unless *dst... == *src...

It seems that no matter the operator used here, the ants just doesn't show up in some area, or the ants just doesn't show up at all.

This line looks weird. Did you mean m_d->outlineCache?

This should use &=. Otherwise it will alwas run regenerate the outline cache.

This should be the same as for the vector selection so m_d->outlineCache = (m_d->outlineCache | selection->outlineCache()) - (m_d->outlineCache & selection->outlineCache());
