This is with build 2002062004 on Win2K Pro w/ SP2. Scrolling down in the browser
with a transparent window over a part of the main browser window causes
artifacts over the rendered page to appear.
See attached image.

This is using a NVidia Riva TNT2 using following drivers:
WINNT\System32\DRIVERS\nv4.sys
WINNT\System32\nv4.dll
Version 5.00.2165.0327
This is stock Dell Optiplex GX400.

As an obervation it should be noted that the artifacts only appear where there
is text or some other non solid color above or below the transparent window.
Scrolling on a solid white background doesn't seem to cause artifacts, although
they could just be white and we can't see them.
However when there is a lot of text or graphics or just content in general in
the vertical space above the transparent window the artifacts are sure to occur.
Doing a select all on the text of the page will cause the text to appear
normally again and the artifact is temporarily 'erased.' More scrolling will
bring it back.

Unable to reproduce with 1.1a (2002-06-11-04) Win2k sp2.
I have a GeForce 256, and use WinTrans for my transparent windows. I made a
window "always on top," alpha-blended the entire window, and had it stick out
over the edge to correctly reproduce the problem. Even with variations, it
worked flawlessly.
What program are you using for transparency? Perhaps they have documented issues.

I just wanted to reiterate that this is with build: 2002062004.
The program that was drawing that partially transparent window is called <a href=
"http://www.dumeter.com/">DU Meter</a>. I am unaware of this program using
proprietary drawing, as far as I can tell its using the Windows
functionality(SetLayeredWindowAttributes).
Furthermore problem did not occur on same machine with same video config with
any of the builds between 1.0 and build 2002061804.

I can no longer get repro on the very same machine. I've upgraded to build
2002062109 and the problem seems to have disappeared.
