I can confirm it does affect the first episode of the Telltale Monkey Island series :(
Well if the wine devs don't get around to fix it, there's always PlayOnLinux. Install it, and use the wine versioning mechanism to install and activate with an old wine version and then switch wine version back to "System". It's not good for wine because these sorts of workarounds means regressions don't get fixed, but it works for me.
