I wonder if the failure might be triggered by timing change, since the intermittent failure already existed. Bug 1554610 added unnecessary compositor window shutdown. It could change the timing.

CompositorBridgeParent::AllocPLayerTransactionParent() creates unnecessary compositor window when creating basic compositor during d3d compositor is available. It seems better to avoid to create unnecessary compositor window.

It seems that amount of intermittent was dropped by Bug 1616174 .

I do not know well about PAPZInputBridge::Msg_ProcessUnhandledEvent. :kats and :botond know better than me.

I can look

Comment 48

[Kartikaya Gupta (email:[e-mail])]

Put a patch on bug 1619299 which should fix the majority of these failures (all the ones dealing with APZInputBridge). There might be other failures but it should be much lower volume. I'll keep this bug open to track any other problems after bug 1619299 lands.

Comment 49

[Kartikaya Gupta (email:[e-mail])]

Bug 1619299 seems to have worked as intended, the volume here is basically zero since that landed. I'll leave this bug open a bit longer to confirm.
