I have been having a similar problem for a while now, very randomly. I am not sure if its the same as described by others.
I cannot reproduce it at will(It seems to happen when moving between windows, especially gnome-terminal, eclipse and guake), but every now and again the IBUS-daemon pegs one CPU core at 100% and all typing becomes very delayed. Today I finally managed to get an strace log of it happening, at least the tail end of it. I did not catch the beginning of the event only the end before it went back to normal, but you can see that it's trying to continuously access an unavailable resource. Please see attached log. ** Attachment added: "Issue log" https://bugs.launchpad.net/ubuntu/+source/ibus/+bug/1248260/+attachment/4121633/+files/ibus.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ibus in Ubuntu. https://bugs.launchpad.net/bugs/1248260 Title: ibus-daemon hogging resources Status in “ibus” package in Ubuntu: Confirmed Bug description: At times, typing becomes very sluggish and I can see ibus-daemon becomes the process consuming most CPU and most memory in the system.
