Been working on fixing numerous display bugs lately — one of them turned out to actually be an ATI display driver issue that was fixed in an update, the other another strange driver quirk with a viable workaround.
Graphics compatibility vs performance has always been a challenge, as a content tool WM is sometimes run on substandard hardware and needs to remain compatible with that… while at the same time, when displaying high resolution output requires real-time performance as well.
I’m thinking WM 2.3 Beta-2 will be released sometime in the next week or so to bump out the changes to everyone!
