Noticed that yesterday there were some kind of updates, briefly ran through the list and remember keywords like OpenGL, Mesa etc.. updated my computer and this morning did a fresh boot and noticed the messup of every single window's titlebar (see attached picture).
Parts of it became transparent, other parts seems to have loaded some distorted information from other parts of the screen or something.. real mess.
Some minutes ago arrived Nvidia update and xorg edgers updates too, installed them rebooted, titlebars still messed up.
I am on Asus n550jv laptop, Nvidia Geforce 750M, Running Ubuntu 13.10 64 bit, latest bumblebee and nvidia 331.49 drivers.
Any ideas what to do to fix the glitch? Thanks Maris
