I have kind of the same problem. When i start up libreoffice writer/calc etc. it hangs, it doesn't get that far that it shows any text, just gray. And thye cpu and memory usage goes from ca. 10percent to 99-100 percent for both, then everything goes really slow.
Even if i try to open new document, it hangs... when i finally get to kill the process, resource usage goes down to normal again. This is on my home computer (new install 12.04), and my work computer(upgrade 12.04 from 11.10).

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.
