Description

7 years ago
I was investigating youtube HTML5 case and found that we rebuilding layer tree every 1-5 seconds (on mobile much often), and that is causing ShadowImageLayers Create/Destroy thingy, which consume bunch of CPU, breaking A/V sync (triggering framedrop) et.c.

Here is backtrace:

Can we fix it somehow in FrameLayerBuilder?
Can you reproduce it in a reduced testcase?
