You have been subscribed to a public bug:
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. All drivers,
software, BIOS, etc. are at latest versions.
