Similar problem. When marching-ants show up, libre-office bottom bar "flashing" as well. CPU usage rising, disk-I/O (writing) rising as well, at steady. CPU at 50% per core, disk-I/O at 200kB/s.
Then, when I go to any other window (ie: gedit, chrome), do some selection, and press Ctrl-C, then "everything goes back normal". -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1001550 Title: LibreOffice Calc causes high CPU usage in Xorg when displaying "marching ants" Status in “xorg” package in Ubuntu: Expired Bug description: To reproduce (on my system): 1. Run LibreOffice calc (I had imported a CSV with 3 columns and about 300 rows) 2. Select any cell 3. Press Ctrl+C to copy 4. "marching ants" selection appears At this point, Xorg is now using 100% CPU on one of my processors. Clearing the selection (by typing in another cell) clears the "marching ants" selection, at which time CPU usage returns to normal. This survives a restart of the application, or a reboot. Same issue will occur. Running Ubuntu 12.04 LTS 64-bit on a Lenovo ThinkPad T61, 4GB RAM, NVIDIA Quadro 140M running the proprietary nvidia driver.
