--- Comment #2 from Béla Gyebrószki <gyebro69 at gmail.com> ---
I can reproduce the problem in wine-1.7.43-166-g39d71c5

Setting the registry key 'ClientSideGraphics=N' under HKCU\Software\Wine\X11
Driver works around the problem for me and zooming in/out with the mousewheel
is smooth again.

The result of the regression test:

    winex11: Use window surfaces for rendering top-level windows.

    It can be disabled by setting "ClientSideGraphics"="n".
