Hi,
I need some help interpreting PulseLogger output. Sometimes I see log messages like this: [947 16ms:0ms] PULSE: 948 [2051ms:201ms] T13 (-2051 +2051ms): Layout Pass T13 (0 +2ms): CSS Pass T13 (2 +147ms): Layout Pass T13 (149 +1ms): Update bounds T13 (151 +0ms): Waiting for previous rendering T13 (151 +1ms): Copy state to render graph T10 (153 +0ms): Dirty Opts Computed T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow shape path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 : Slow background path for null T10 (153 +47ms): Painting T10 (200 +0ms): Presenting Counters: NGRegion renderBackgroundShape slow path: 12 NGRegion renderBackgrounds slow path: 22 Nodes rendered: 1086 Nodes visited during render: 1159 [949 175ms:65ms] Pulse 948 shows an initial Layout Pass starting at -2051ms. Does this Layout pass with its negative starting point really belong to pulse 948, or is this a bug? The project has a single scene. I’m running this on a mac (OS X 10.12.6) with java 1.8.0_112-b16 (Java HotSpot(TM) 64-Bit Server VM (build 25.112-b16, mixed mode)) with Options: -Djavafx.pulseLogger=true -Djavafx.pulseLogger.threshold=100 Thanks Toni Epple
