Created attachment 472031 [details] animation-blur-slow.html When running animation-blur-slow.html demo using GTK port with some log instrumentation, one can see the damage information is constantly empty after few frames: LayerTreeHost::didRenderFrame(): damage - isEmpty():1, isInvalid():0, rects#:0, bounds:(0,0,0,0) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(0,0,2560,1357) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(0,0,2560,1357) LayerTreeHost::didRenderFrame(): damage - isEmpty():1, isInvalid():0, rects#:0, bounds:(0,0,0,0) LayerTreeHost::didRenderFrame(): damage - isEmpty():1, isInvalid():0, rects#:0, bounds:(0,0,0,0) LayerTreeHost::didRenderFrame(): damage - isEmpty():1, isInvalid():0, rects#:0, bounds:(0,0,0,0) LayerTreeHost::didRenderFrame(): damage - isEmpty():1, isInvalid():0, rects#:0, bounds:(0,0,0,0) LayerTreeHost::didRenderFrame(): damage - isEmpty():1, isInvalid():0, rects#:0, bounds:(0,0,0,0) LayerTreeHost::didRenderFrame(): damage - isEmpty():1, isInvalid():0, rects#:0, bounds:(0,0,0,0) Moreover, when running animation-blur-fast.html demo the same way, one can observe the damage information that is too small (should be larger than 100x100): LayerTreeHost::didRenderFrame(): damage - isEmpty():1, isInvalid():0, rects#:0, bounds:(0,0,0,0) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(0,0,2560,1357) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(0,0,2560,1357) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100) LayerTreeHost::didRenderFrame(): damage - isEmpty():0, isInvalid():0, rects#:1, bounds:(1230,100,100,100)
