Add the following to your eclipse.ini:<p>--launcher.GTK_version
2<p>Alternatively set the environment variable SWT_GTK3 to zero to launch eclipse:<p>export SWT_GTK3=0; &#x2F;path_to_your_eclipse&#x2F;eclipse<p>As a side benefit:
GTK2 with a compact theme will also make a much better use of your screen real estate. Especially important, if you want to work on laptop with a small screen diagonal.
GTK3 as it comes out of the box is just ridiculous in this regard. Eclipse is completely unusable with GTK3 on my 1200x800 12&quot; machine because of that.
