It seems that this bug is also cause of the Eclipse 4.x crashes (and high CPU load and hanging) https://bugs.eclipse.org/bugs/show_bug.cgi?id=397291
I have maybe 10 dumps beginning with the following: # SIGSEGV (0xb) at pc=0x00007fe9bb3dd92a, pid=7396, tid=140643637405440 # # JRE version: OpenJDK Runtime Environment (7.0_51) (build 1.7.0_51-b00) # Java VM: OpenJDK 64-Bit Server VM (24.45-b08 mixed mode linux-amd64 compressed oops) # Problematic frame: # C [libgtk-x11-2.0.so.0+0x24492a] gtk_widget_queue_draw+0x1a # The XAA Option evidently helped. Firefox did not crash before this change and does not crash even after that. Eclipse did not crash after this change and is much faster (does not slow down after hours of work on the big workspace). Kubuntu 13.10 64bit, Dell Latitude E6520 with i5 CPU. ** Bug watch added: Eclipse bugs #397291 https://bugs.eclipse.org/bugs/show_bug.cgi?id=397291 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/238629 Title: [i965] Java plugin causes massive Xorg CPU usage, fixed with XAA (UXA/EXA) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/238629/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
