After removing clips by default, the OpCount of a picture drops significantly. That makes our old threshold suboptimal. The new threshold reflects the clip change and will improve our scroll performance by ~10% for complex_layout and flutter_gallery scroll benchmarks: (flutter_gallery) home_scroll_perf frame raster time: average 9.1ms -> 7.4ms 90th_percentile 11.3ms -> 9.2ms 99th_percentile 45ms -> 38ms complex_layout_scroll_perf frame raster time: average 4.8 -> 4.4ms 90th_percentile 7.8ms -> 5.4ms 99th_percentile 19ms -> 17ms This should also help mitigate issues like https://github.com/flutter/flutter/issues/24782
Flow
Flow is a simple compositor based on Skia that the Flutter engine uses to cache recoded paint commands and pixels generated from those recordings. Flow runs on the GPU thread and uploads information to the GPU.
