clip of bad and good controls

In some applications (namely PowerDesigner, MSOffice 2007) there are GUI
controls incorrectly painted. The attached picture shows a bad and a good case.

Using git bisect I have found that problematic commit is
c29cf0591976f96c3adb30c3c3b6db59f4983251 - winex11: Add support for 32-bit DDBs

I also verified that git revert of villain patch on the current master branch
(5815b639794fa5e8e79754d86b66c6a03596731d) really corrects the problem.

I have tested that the problem is not in the placement of wine_tsx11_lock call.
I moved it before the line 
 if (!X11DRV_XRender_SetPhysBitmapDepth( physBitmap, bitmap.bmBitsPixel, NULL
...
but the problem remained.

Currently I have no clue where the problem could be. I will continue in
investigation, but may be someone who is more experienced could find the origin
of problem immediatelly.
