wine users - Dec 2010 - Window scrolling artifacts in PDF XChange Viewer

I'm seeing some really annoying behavior in Tracker Software's PDF
XChange Viewer (http://www.tracker-software.com/product/pdf-xchange-viewer)

When I scroll the window in either direction, I get artifacts from the window
frame as evidenced by this screenshot

I've tried Foxit too, and it doesn't seem to do this.

Does anyone have any suggestions on how to make it go away?

I'm using the 64-bit edition of Ubuntu 10.04.

I've tried the version of Wine 1.2 that exists in Ubuntu's repository
and the versions of 1.2 and 1.3.9 in WINE's launchpad PPA as of yesterday.

I used the EXE installer for PDF XChange.

Hi,

You may try to install previous stable release (2.057) downloaded from
http://www.tracker-software.com/product/downloads. I solved the same problem by
doing so.
