----------------------------------------
Summary: Screen sharing for SSH broken by GUACAMOLE-176
Key: GUACAMOLE-226
URL: https://issues.apache.org/jira/browse/GUACAMOLE-226
Project: Guacamole
Issue Type: Bug
Components: guacamole-server
Reporter: Michael Jumper
Priority: Blocker
Fix For: 0.9.12-incubating
GUACAMOLE-176 added support for layer opacity to the {{guac_common_surface}}
object. Although layers always default to opaque, the {{opacity}} property of
{{guac_common_surface}} is not properly initialized to fully-opaque (0xFF).
Layer opacity is not sent to the original user of a connection unless it
changes, so the original user is unaffected, but any users which _join_ a
shared connection will be synced with display state, including the incorrect
opacity. For VNC and RDP, only the default layer is used and this bug has no
effect, but SSH (and telnet) use multiple layers.
