sshot of the problem on QtLauncher

I am trying the backing store (bug 35146) on QtLauncher, and I've facing issues
w/ tiles not being update w/ fast scrolling (via mouse wheel). for example, in
slashdor.org I end up w/ the attached situation.

steps to reproduce (on Linux 32bits, qt4.7):

1 - enable graphicswebview and tiling QtLauncher.
2 - go to slashdot.org, and wait for it to load completely.
3 - scroll to the end of the page, where problem is better reproducible.
4 - resize QtLauncher window (I usually make it a bit bigger than default size)
5 - do some fast scroll up/down w/ mouse wheel or (vertical scrollbar).


note that if I do not resize the window in step (4) bug is hardly reproducible
for me.
