Created attachment 32360 [details] Testcase The attached testcase shows an issue where an element is not correctly repainted after dropping out of compositing mode. To reproduce: 1. Hover over the pink square and wait for the elements to stop transitioning 2. Unhover. 3. Note how the "width" box does not redraw correctly. The issue is that m_repaintRect which is cached inside the RenderLayer was computed relative to the compositing ancestor, and that ancestor changes when the layer ceases to be composited.
