SpoiledTilePercentTotal (Total percentage of the content that did not reach the viewer but was instead discarded and overwritten by fresh content)  > 36
RDPTileProcessingLatencyAverage (Average processing time for remote desktop protocol (RDP) tiles. A higher total equates to a longer delay in the viewing experience) > 400
