--------------------------------------
Resolution: Done
Fix Version/s: 0.9.12-incubating
> Update layer properties only on flush
> -------------------------------------

> Key: GUACAMOLE-177
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-177
> Project: Guacamole
> Issue Type: Improvement
> Components: guacamole-common-js
> Reporter: Michael Jumper
> Assignee: Michael Jumper
> Fix For: 0.9.12-incubating
>
>
> 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).
