--- Comment #11 from Matthew matthew.rathbone@gmail.com 2012-03-21 12:01:27 CDT --- Hey Henri,
as per the above comment, looks like there's some sort of memory leak when interfacing with newer AMD/ATI cards.
Not sure if this was brought about by your patch, or whether it's something deeper down [maybe not even in wine?]
Do you have any insight to offer us? Maybe tweaking some specific configs can fix it?
