http://www.winehq.org/pipermail/wine-patches/2012-February/111811.html should fix it.
Hi Dmitry,
The patch did fix the flickering issue for me, but I noticed a few new oddities with the treeview scrollbars in regedit after applying it:
1. When regedit is first opened, a horizontal scrollbar is present even though there's no need to scroll.
2. Expend HKEY_CLASSES_ROOT, then select it. A vertical scrollbar should appear. Now close and reopen regedit - HKEY_CLASSES_ROOT is still expanded, but the vertical scrollbar has disappeared.
