Previously, the RRSelectInput() function failed to perform endian conversion correctly. Consequently, some gtk2 applications run on a little-endian architecture but displayed on a big-endian architecture - or vice versa - terminated unexpectedly with the "BadValue (integer parameter out of range for operation)" error message returned. A patch has been applied to address this issue and the applications now run correctly in the described scenario.

Previously, running multiple xterm processes generating large amounts of text caused a memory leak in the X server. Consequently, all available system RAM could be consumed over time. This update fixes the composite wrapper code that was leaking certain region structures and the X server no longer leaks memory in the described scenario.

Previously, the RRSelectInput() function failed to perform endian conversion correctly. Consequently, certain GTK+ 2 applications run on a little-endian architecture but displayed on a big-endian architecture - or vice versa - terminated unexpectedly with the "BadValue (integer parameter out of range for operation)" error message. This problem has been fixed in this update so that the applications now run correctly in the described scenario.

An unexpected termination in software image transfers on 64-bit systems that caused the X virtual framebuffer (Xvfb) to terminate unexpectedly with a segmentation fault has been fixed.

Previously, when the number of server clients changed from >0 clients to 0 clients, if started with neither the "-noreset" or "-terminate" flags, Xvfb consumed more memory than expected. With this update, this bug has been fixed.

When using a direct XDMCP query to connect to a Red Hat Enterprise Linux 6 server, the X server terminated unexpectedly with the SIGBART signal. The same problem affected Xephyr and Xnest. With this update, the bug has been fixed so that the X server, Xephyr, and Xnest run properly after connecting to the server with a direct XDMCP query.

Previously, there was a memory leak occurring in the X server when running four xterm instances with scrolling data on each of them. This bug has been fixed in this update so that the memory leak in the X server no longer occurs.

Previously, there was a bug in the X server preventing users from switching a graphical screen to a text screen. As a result, users were unable to use a graphical screen and a text screen in the same session. With this update, the problem has been fixed and does not occur anymore.

When rebooting or shutting down the system, a screen with the reboot or shutdown messages was not displayed. With this update, the bug has been fixed so that the screen with the messages is displayed correctly when rebooting or shutting down the system.

When logging out of the graphical session on a system with NVIDIA or AMD graphics cards using the DisplayPort interface, a fatal X server error occurred and a backtrace was logged into the X server log file. With this update, logging out on the mentioned systems works as expected and the error no longer occurs.

On certain HP ProLiant DL380e Gen8 Server configurations, switching to a different virtual console, or switching to runlevel 3 from runlevel 5, or shutting down the system from runlevel 5 did not work correctly. With this update, the problem has been fixed and the system behaves as expected when performing the mentioned operations.
