REGRESSION(112745) [CSS Filters] Memory use explosion for offscreen filtered elements https://bugs.webkit.org/show_bug.cgi?id=83815 Reviewed by Simon Fraser. Source/WebCore: The filtered area used to be the dirty rect intersected by the bounding box of the layer. During a previous change that behavior was lost, so adding it back now. Also, removing the memory buffers used to compute filters after the filter is computed. They are deleted next time the filter is applied anyway, so there's no need to keep the memory for them. Test: css3/filters/offscreen-filters-memory-usage.html * rendering/FilterEffectRenderer.cpp: (WebCore::FilterEffectRenderer::prepare): (WebCore): (WebCore::FilterEffectRenderer::clearIntermediateResults): (WebCore::FilterEffectRendererHelper::prepareFilterEffect): (WebCore::FilterEffectRendererHelper::applyFilterEffect): * rendering/FilterEffectRenderer.h: (FilterEffectRenderer): LayoutTests: Adding a test that creates a lot of layers outside the viewport. The memory should not grow and the browser should not crash. * css3/filters/offscreen-filters-memory-usage-expected.txt: Added. * css3/filters/offscreen-filters-memory-usage.html: Added.
