In https://bugs.webkit.org/show_bug.cgi?id=80323 I fixed the drop-shadow and blur repainting issues by using the whole image of the layer and not just the dirty rectangle. That seems to introduce a memory regression on some sites. In this patch I will disable the previous fix until we have a proper fix for https://bugs.webkit.org/show_bug.cgi?id=81263.
