Hi,

I believe that WinCairo/any other ports using Cairo currently suffer from a graphical corruption when clipping inside a rotating div. I don't have the latest WinCairo binary but one from few months ago shows the problem. I searched BugZilla and did not find any relevant bugs. Test page attached here.

So my original message was only halfway finished...

I believe the problem is only in Cairo related ports though I could be wrong. If somebody can point me towards code to look at, I can investigate it in our local fork and update the community with my findings.

Thanks for your time.
