I happened to realized that there's same assertion bug, bug 1712001. I wonder it's a pr-exisiting issue?

Whiteboard: [retriggered][stockwell needswork:owner]

I did track down what's going on. The crash actually happens at this debug_assert!(info.ignore_missing_pipeline) assert. The missing pipeline id comes from this PushIFrame command in WebRenderImageData::CreateAsyncImageWebRenderCommands. The pipeline id in Scene.pipeline has already been in fact removed by the ClearCachedWebrenderResources call introduced in bug 1742797.

I believe this is a pre-existing issue, because when we recreate popup we do call ClearCachedWebrenderResources and it happens on Macs if the device has multiple screen.

CCing sotaro.

I think we were hoping to use this bug to actually address the underlying issue (which a backout of the patch that happens to trip this condition in automation doesn't really do), per comment #6. Without doing so, we can't reland the patch in 1742797 so we're a bit stuck. That is bad because of the perf issue that 1742797 would address, which it would be very nice to fix soon. Jeff or Sotaro, can you take a look, per comment #6, as to what is happening here?

I am going to look into the problem.

Flags: needinfo?(sotaro.ikeda.g)
Assignee: nobody → sotaro.ikeda.g

In WebRenderBridgeChild, WebRenderBridgeChild::SendParentCommands() is called after WebRenderBridgeChild::SendClearCachedResources(). And WebRenderBridgeParent::RecvClearCachedResources() does clear resources by using low priority resources.

Then WebRenderBridgeParent::RecvParentCommands() is called after the RecvClearCachedResources(). But root WebRenderBridgeParent normally handle txn without using low priority txn. Then there is a case that WebRender handles the txn before the clear resources.

It seems necessary to handle removing async image pipeline id by using low priority txn.
