Are you having problems viewing the map and journal and such - they are all black except some icons correct? This is usually a sign for a corrupted save - especially if they are blacked out, or don't appear normal, most of the time (from my experience anyway) this is a sign of a save that could have future problems. Then again I don't have Windows 7, but Vista so either way you might have fixed it, or just temporarily halted it.Strange that restarting fixed it for you ockzon, I've never had to resort to that and its pretty pointless to do, because if you only encountered it as you progressed - it slims it down to these two factors:a) its either hardware related, i.e your hardware could be overheating, or not functioning properly and displaying this - either new hardware are fixes or latest updates - If you don't have problems playing other games visually, then it knocks a) out the window.b) its an element of your save, some choice you made or decision, since there are so many possibilities, unfortunately people have found an array of bugs. My theory is that every quest/interaction and completion of quest, as well as time they are completed (say if they are completed in the same time as another or while one is in progress) all these factors, may or may not give you bugs while playing. It's a really good game but the witcher was created from quite a new developer, there is no definite way to avoid them..I noticed you stated you reverted to a save, if more problems persist with that save, in later chapters perhaps - all might be well and you may not spot anything. But if they do, then revert to an even older save, save frequently, before and after each major step you take and monitor your progress, keep an eye out for unusual things.There probably won't be fixes for these bugs, The Witcher 2 is already released, keep us posted, and constantly save!
