> The Guacamole client and display currently queue up all drawing operations such that they are committed only when a frame is flushed ... except for changes which update layer properties like location and opacity.
> For the sake of consistency and performance, any change which affects the contents of the display should be deferred until the display state is actually flushed due to a "sync" instruction. Doing otherwise leads to incomplete display state (partial frames) and slower performance (unnecessary operations, excess computation between frames).
