!!! FIXED: Very slow scrolling on log entries table !!!

Post by admin » Sun Sep 27, 2009 10:18 pm

If you use:
- Windows XP/Vista/7, and
- Java 1.6.0_u10 or greater (1.6.0_u16 so far),
you may experience very poor performances when scrolling main log entries table (for all LogMX versions).
This is due to a known Java bug appeared in 1.6.0_u10 dealing with Direct3D and XOR paint mode.

To fix the problem, start LogMX with the system property "sun.java2d.d3d" set to "false" to turn off the use of Direct3D.
To set this property, modify files "launcher.cfg" and "LogMX.bat" (in LogMX install directory) by adding "-Dsun.java2d.d3d=false" just before "-Xmx302m".
Examples:

Code: Select all

SET JVM_OPTIONS=-Dsun.java2d.d3d=false -Xmx302m %CONFIG_FILE_PATH%
-Dsun.java2d.d3d=false -Xmx302m -cp classes\;parsers\classes;managers\classes;jar\logmx.jar;lib\xtlnf.jar;lib\jsch.jar;lib\activation.jar;lib\mailapi.jar;lib\smtp.jar;lib\jcommon-1.0.14.jar;lib\jfreechart-1.0.11.jar com.lightysoft.logmx.LogMX

For further information, please see:

The next release will of course disable use of Direct3D by default (next releases will allow use of Direct3D only if the used Java version contains a fix for this bug)

LogMX v2.0.0 is now available, and include a fix for this bug (Direct3D now disabled), among many other new features (http://www.logmx.com/p_download.php#ChangeLog).
