  "message": "Fix some issues in the integration between EmbedderExternalViewEmbedder and Impeller (#184905)\n\n1) Fix inaccurate Impeller rendering of embedder layers containing\nmultiple Flutter content slices.\n\nAll of the Flutter content slices within a layer will be merged into a\nsingle display list. The display list is then rendered with one call to\nimpeller::RenderToTarget.\n\nBefore this change, each Flutter slice in a layer made its own call to\nimpeller::RenderToTarget. This caused earlier slices to be overwritten\nby the output of later slices.\n\n2) Pass reset_host_buffer\u003dtrue only for the frame\u0027s last call to\nimpeller::RenderToTarget\n\nSetting the reset_host_buffer flag advances to the next device buffer\nwithin the impeller::HostBuffer associated with the Impeller context.\nThis should only be done at a frame boundary after all of the frame\u0027s\ncontent has been rendered.\n\nSee https://github.com/flutter/flutter/issues/184091",
