We are sorry you are experiencing those issues. On the other hand take into account the context of this bug is very specific, and libre drivers will work better in nearly any situation.
In fact I own a Radeon HD5870 and I have been using libre drivers much before proprietary ones were deprecated, because of their advantages. Modern cards even have better support than that.
