--- Comment #3 from Roland Grunberg rgrunber@redhat.com ---
The bug has been reported upstream ([GTK3] Eclipse Mars SR1 consumes 60% CPU while idling) : https://bugs.eclipse.org/bugs/show_bug.cgi?id=478962 And is fixed in master : Gerrit change https://git.eclipse.org/r/61124 was merged to [master]. Commit: http://git.eclipse.org/c/platform/eclipse.platform.swt.git/commit/?id=87d512...
I use eclipse-swt-4.5.1-6.fc23.x86_64 on Fedora 23.
I'm also seeing roughly the same thing, except for me it seems to stay at around 40-50% while idle. Minimizing the window has it dropping to ~1%
The bug and patch you mention were backported as 4.5.1-6 (http://pkgs.fedoraproject.org/cgit/eclipse.git/commit/?id=f2e612a4c062c77352...), but I've just learned from Eric that there was another issue causing cpu consumption while idle. (See https://bugs.eclipse.org/bugs/show_bug.cgi?id=484729) . It was introduced by a patch that we backported into 4.5.1.
It's currently being tested, and should find its way into f23 soon.
