This is a kinda weird question I don't know what to file it under but this is the behaviour I observe when I try to access pages like facebook (it happened once with google as well. Happens with tumblr now too).
This is a new thing so I haven't really tried to figure out which pages trigger this, I just switched to firefox which seems to work ok (because I am in the middle of some work that needs to be done without interruptions.
The first time this occured I left the page open and tried to figure out what happened the whole graphics turned off and it went to terminal.
I recently installed a ram dimm (if you think that might be somehow related)
CPU: Intel® Pentium(R) CPU B960 @ 2.20GHz × 2 64bit
GPU: Intel® Sandybridge Mobile
Thanks in advance!
edit: appears to be happening with bookmark manager as well!
