Poor X11 Emulation Performance on Windows Multi-Display Clients after Applying PSU 7 to SGD 5.2
Last updated on MAY 15, 2018
Applies to:Oracle Secure Global Desktop - Version 5.2 and later
Information in this document applies to any platform.
Users connecting to Secure Global Desktop (5.2) with Windows, multi-display clients may report poor application emulation performance when running X11 applications (Linux, Unix) after the recent installation of the October 2016 Patch Set Update (PSU), commonly referred to as PSU 7.
This behavior is most often described as an "unresponsive mouse," wherein users may report that they are unable to interact with runtime application menus once they have been activated and "dropped down." This condition may be exacerbated when applications are moved to a secondary display after launching, though this is not necessarily a prerequisite for the condition.
Additional symptoms of this class of behavior may include:
- Most likely to impact Windows clients where the primary monitor is not the top-left.
- Unable to select objects within drop-down menus.
- Clicking anywhere within provisioned application selects the entire application window.
- The application window "turning white," after dragging or resumption to a secondary display.
This change in behavior has been directly attributed to changes included within PSU 7 for SGD 5.2.
