Repainting after scrolling was a bit lazy, and creating a new
project still requires ie6, but it was a nice surprise all the same.
I wouldn't be too surprised if that was a VS2005 bug, not a Wine issue -- it
also has horrendous redraw problems running under Vista with Aero/DWM, for
instance. http://forums.asp.net/p/1088151/1624585.aspx is an example
complaint I found when doing a is this just me? search last year.
The laziness isn't too bad - it's in the text area, happens when scrolling,
and clears itself within a tenth of a second. We're probably just not
handling bitblt fast enough, or something?

What version of Wine and display drivers are you using? In 1.1.26 I
added a bunch of XRender related patches to accelerate already big
chunks of bitblt (less roundtrips to X are needed). In some situations
it can already boost performance a lot depending on the display
drivers. There are more bitblt improvements possible though. For
example in case of SRCCOPY, which is the most common blit operation, I
can save a 'memcpy' by getting rid of an intermediate buffer.
I have some more patches which can dramatically improve rendering
performance soon in cases where programs hit dibsection depth
conversion.
I can't easily say what is making Visual Studio slow but I guess it is
a combination of slow drivers (fglrx is quite slow) and bitblt
slowness.
