New Features and Resolved Issues

This release includes features and fixes previously released in version 5.1, as described in KB 7021837, plus the following additional features and fixes:

Performance Improvements

The following features are performance improvements to reduce X session startup time when using an RXA domain:

  • The visible X server run on the X Manager for Domains workstation is now constructed locally rather than being transferred from the domain node.
  • On sessions configured for fault-tolerant remote session services, or configured for always-enabled compression, latency and bandwidth (respectively) are now measured at reduced intervals.
  • On high latency networks, sessions utilizing remote session services now start faster due to reduced communication between X Manager for Domains and the domain node.

Resolved Issues

  • Pauses in X applications no longer occur due to bell tones being played.
  • The middle mouse button emulation feature has been corrected to properly report button events while the X application holds a pointer grab. UI fields relating to configuring this feature are also now enabled or disabled correctly.
  • Possible out-of-memory conditions are now avoided by limiting the maximum number of threads started by certain thread pools.
  • Two X sessions running in the same domain node or X Manager instance can no longer hang due to a deadlock when opening or closing font files.
  • On a multi-monitor workstation, the Reflection Window Manager now constrains windows to visible space when the X application specifies a location that would result in any part of the window being invisible.
  • Keyboard focus in X applications is now correct when the native OS clipboard contains content in unsupported formats.
