To reiterate, the problem is not the lack of BeginPaint/EndPaint but
rather the fact that some apps are not validating the invalid region for
some reason. BeginPaint/EndPaint do this for you, but they aren't the only
way (which is why Foobar2000 can get away without it).

In particular, Notes has regressed as well so I will be working on this. I
might take a look at Foobar2000 as well to see if I can figure out if it's
a similar problem or a different one.

Unfortunately we don't really understand what's going on here. There may
be one bug, there may be *many* bugs all that cause the same behaviour. So
I'm afraid it's not something that will be fixed overnight.
