Build Identifier: I20110613-1736 Any tooltip window takes 5-10 seconds to display causing a 100% CPU load, and a UI lock up. This problem appears in different editors from different plugins and seems to be rooted in the Eclipse UI itself - editors causing problem: PyDev *.py, Web tools HTML/CSS editor. Following suggestions in other bug reports I've disabled Appearences > Animations. This has no effect. Using jvisualvm I was able to capture a stacktrace as well as a sample profile of the hang.

For reproductibility I believe it is important to open Eclipse in a Gnome environment.
Affects both Eclipse 3.6 and 3.7, haven't tested on earlier versions.
Think there might be another bug on this.
I've found these: https://bugs.eclipse.org/bugs/show_bug.cgi?id=354842 https://bugs.eclipse.org/bugs/show_bug.cgi?id=354842 but in the case of the first the workaround (disabling animations) doesn't really have any effect. The latter case looks indeed similar, but the native function call and the stacktrace look different, so I'm not entirely sure.

Hello, Could I at least get a confirmation on whether or not this affects all Linux installations with Gnome3 or is it just my particular case? If it affects all of them I seriously think this is a *very* *very* important issue. Gnome3 is gaining popularity among various distributions. It will be available in Ubuntu in the next release. And I kid you not, Eclipse is unusable with this bug in place. You have to wait for completion dialogs. You have to wait for annotation hints, you have to wait for in-code symbol hints. You have to wait and wait, and the CPU gets hot. I mean, if each time this happens one has to wait for 5-10 seconds, I don't think it's very likely people will stay on Eclipse.
I don't see the problem with Eclipse running on Ubuntu 11.04, Unity desktop. I haven't tested with GNOME 3 yet but I'll try to do it and then provide an update about the same.

To test it with Gnome 3 you need to actually install Gnome 3 from PPA. Also note that this breaks Gnome 2/Unity installations, however is reversible.
(In reply to comment #10) > > To test it with Gnome 3 you need to actually install Gnome 3 from PPA. Also > note that this breaks Gnome 2/Unity installations, however is reversible. I tried installing GNOME 3 from PPA and ended up with a situation where neither Unity nor GNOME 3 was loading properly! Luckily, it was a virtual machine setup and so I'm gonna uninstall and reinstall and give it another try.

Bumped up priority since Eclipse is unusable with this bug.
Still an issue with eclipse 4.3RC4 (Build id: I20130605-2000).

This is on an up to date Ubuntu 13.04 64bit. $ uname -a Linux gf213240 3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:07 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/issue Ubuntu 13.04 \n \l Regards, Patrick.
Or is it a false positive? As this is inside an 'eventLoopIdle' method call, it may the expected behavior. Anyway, eclipse 4.2/4.3 is slow on Ubuntu 13.04, the UI freezes for several seconds every now and then. Regards, Patrick.
It's happening to me with Eclipse Luna Version: 4.4.0 Build id: 20140612-0600 on Windows 7 Ultimate in the java editor only when hovering over problems, if I disable Preferences > Java > Editor > Hovers > Problem Description, hovering docs or source is quick.
Same problem occurs in Eclipse Kepler running in Centos. In Kepler i use lots of plugins like team, findbug,hibernate,etc linux version 2.6.18-274.18.1.el5.centos.plusPAE following from .log in matadata:- eclipse.buildId=4.3.2.M20140221-1700 java.version=1.7.0_65 java.vendor=Oracle Corporation BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_US Eclipse hangs after every few minutes so by visualvm i try to understand whats going on. I see org.eclipse.swt.internal.gtk.OS.call[native] & org.eclipse.swt.internal.gtk.OS._gtk_tree_model_get_path[native] org.eclipse.swt.internal.gtk.OS._gtk_tree_store_set[native] org.eclipse.swt.internal.gtk.OS._gtk_tree_model_get[native] utilizing CPU self time in sampler. So now i use Eclipse Luna without any plugin for just for compile & run my code. i afraid to download any plugin in Luna due to cpu utilization.
For me eclipse 4.4 hangs occasionally on Ubuntu 14.04 with openjdk 1.7 when opening menus from the menubar. From visualvm it seems all cpu is used around this: "main" prio=10 tid=0x00007f799000a800 nid=0x4627 runnable [0x00007f79991ba000] java.lang.Thread.State: RUNNABLE at org.eclipse.swt.widgets.Display.asyncExec(Display.java:734) - locked <0x0000000601c8dae8> (a java.lang.Class for org.eclipse.swt.graphics.Device) at org.eclipse.ui.texteditor.AbstractTextEditor$ActivationListener.windowActivated(AbstractTextEditor.java:1006) at org.eclipse.ui.internal.Workbench$11.run(Workbench.java:1045) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.internal.Workbench.fireWindowActivated(Workbench.java:1042) at org.eclipse.ui.internal.WorkbenchWindow$14.shellActivated(WorkbenchWindow.java:2272) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:88) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4486) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1388) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1412) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1393) at org.eclipse.swt.widgets.Shell.filterProc(Shell.java:759) at org.eclipse.swt.widgets.Display.filterProc(Display.java:1586) at org.eclipse.swt.internal.gtk.OS._g_main_context_iteration(Native Method) at org.eclipse.swt.internal.gtk.OS.g_main_context_iteration(OS.java:2473) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3439) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:1151) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:1032) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:148) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:636) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:579) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:150) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:135) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:134) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:104) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:382) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:236) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:648) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:603) at org.eclipse.equinox.launcher.Main.run(Main.java:1465) at org.eclipse.equinox.launcher.Main.main(Main.java:1438)
I should add that the menu does not become visible - only the dropshadows of the menu become visible. One can still click outside and close the menu but from then on eclipse is unresponsive.
A hang like this in Shell.createHandle() would be visible all over SWT/Eclipse. I can't reproduce something like this using either Neon or some of the early 4.7 builds. Marking as closed, please re-open if the issue persists. There were a lot of GTK3 fixes in Neon, please try the stable Neon release or a nightly build for 4.7 to see if the issue is still present.
