> Most things are okay.  I am experiencing a lot of corruption on vertical scrolling; some rectangular areas of the display don't redraw.  This is particularly ugly when editing a source file, because I am never sure where I am clicking or selecting.  It is most noticeable on a small scroll such as you get with the scroll wheel.  I see it also when scrolling a web page in a browser.  It tends to be reproducible if you scroll down and then up one scroll wheel click.  If I bring up a .jpg in the browser, I get some rectangular areas where the image is white.  If I then do a "back" and "forward" to get it redrawn, it is completely drawn.  I know this is not the best description, but I am looking for guidance on where to look first.

in that case does the combination of xserver 1.8 + mesa 7.7 work for
