I have seen this when just browsing around and scrolling with the scrollwheel, but here is a reproducible case.

In the attached example hit Ctrl-F to cause the search widget to appear and the webview to scroll down.  The left hand side of the webpage flickers between white and painting the webpage.

If I turn off updates (see the two commented out lined in main.cpp before calling setScrollBarValue the flickering goes away.

Could not reproduce on Windows with Qt 4.7.

Since this bug is quite old I'll assume that it is not valid anymore and resolve it.
Please tell if you can still reproduce the bug.
