This but is created by Bug 1504230 Comment 9.

In the following STR, there was a case that video was not rendered.

[1] Start firefox and start playback video.
[2] Open new window by dragging new tab and start playback video.
[3] Open new window by dragging new tab and open "about:support".
[4] Close GPU process by pushing "Terminate GPU Process" button.
[5] Check Tabs that were playing videos if video is rendered correctly.

During re-creating GPU process, there was a period that ImageBridgeChild was re-created, but ImageBridgeChild::UpdateTextureFactoryIdentifier() was not called yet. In the period, if ImageBridgeChild::CreateImageClient() is called, ImageBridgeParent creates incompatible ImageHost than WebRenderImageHost.
