Hi Richard and Niklas,
here are the results of pulseLogger for a simple click of a ToggleButton in a
StackPane:
PULSE: 3 [12259ms:306ms]
T1 (1 +27ms): CSS Pass
T1 (28 +0ms): Layout Pass
T1 (28 +0ms): Waiting for previous rendering
T1 (29 +0ms): Copy state to render graph
T7 (56 +1ms): Dirty Opts Computed
T7 (60 +241ms): Painted
Counters:
Nodes rendered: 3
Nodes visited during render: 3
So how can we interpret these results?
Best,
Tobi
