--- Comment #4 from A Wine user RandomAccountName@mail.com 2010-04-20 13:38:42 --- Created an attachment (id=27476) --> (http://bugs.winehq.org/attachment.cgi?id=27476) Paint.NET 2.5 screenshots
IMO, just because something is broken already doesn't mean it should be left to accumulate extra problems... I noticed that the installer for Paint.NET 2.5 is hit harder by this: it was only slightly corrupted before, but now about half of the screen is unreadable.
If you don't think it's really a regression, though, I won't push the issue any further. I haven't found anything that worked correctly before which is affected, and the same commit fixed at least one bug that I know of.
