I did some testing with Carlos' patch to bug 215445. As the patch uses backdropFiltersRect as the clip rect when painting the backdrop layer, this bug gets fixed as well. Great.

I'm still working on bug 215445, as there are some details missing in the patch, and some tests that aren't passing. I'll send a new patch for it and close this when the other bug gets fixed.

Thanks for the patch anyway Fujii!
