I just upgraded my system to Ubuntu 12.04 on Fri., everything works great but Chrome is giving me issues with most pages.
As you can see the graphics in that tab are frozen sort of. If I switch tabs after loading the page and go back to that tab then it looks fine. But for instance on FB if I scroll down and play with any menu item or the advisory icons at the top, it won't popup. I have to switch screens and come back and it then comes up that menu item.
Chrome version is 23.0.1271.97. I can't figure out if this is an issue with the latest Chrome and how to fix or if this is an XFCE problem or Graphics card problem.
I can play games just fine so I don't think it's that. I do remember that in Gnome before switching over to XFCE under the new Ubuntu I had window cutting problems while dragging windows over the desktop. But XFCE doesn't have this problem.
Also if I open any of the pages I have problems with in FF I don't have these same problems.
