A possible solution from John Harris:
A solution seems to be to create a "ini" configuration file and tune the software stack to the local environment.
Of particular importance is the last line. [ -Dorg.eclipse.swt.internal.gtk.cairoGraphics=false ]
Contents of working 'ApacheDirectoryStudio.ini' for Linux, located in the product directory, as per the install guidelines;
## This is the magic line, the rest is site and product specific, as required.
To start, you can copy and paste this into a "INI" file and tune as required.
Strip out the comments not required and adjust your settings (Xms / Xmx / XX:MaxPermSize ) as required.
This is a minimal solution, please refer to the Java manuals and guides for a complete list of options.
Please be conservative, at least to start.
Modify a line at a time, an option at a time.
Should you not need anything else, leave it out.
Also disable any other workaround that you may have active, including the ones noted for 'DIRSTUDIO-962'.
This was tested on a Centos 6 (workstation) x86-64 platform with 16GB of memory using a Tyan S7002 Mobo with Dual xeons running a slightly modified KDE.
However, providing your hardware is stable, hardware shouldn't be an issue.
The issue at hand appears to be the recent GTK upgrades to Debian, Redhat and related platforms.
This fix also seems to work on prior legacy Eclipse based platforms before Eclipse Luna.
I would also assume, but have not tested on all such products, that this would work on legacy Eclipse platforms that utilise legacy (prior to Luna) Eclipse.
I.E. Aptana Studio, Zend Studio, LibreSource, the IBM eclipse based Tools, etc.
For other platforms, refer to their guidelines for creating an "INI" file and it's correct location.
However, as that may be, the only way to find out, is to throw it out there and test it.
Some feedback, Good, Bad or Indifferent, would also be good, guys.
This works for me in: Apache directory Studio (Version: 2.0.0.v20130628) for Linux.
