Comment 56 for bug 681915

I have a ThinkPad X200 with Intel 4500MHD graphics, and occasionally I have experienced the same kind of display corruption in the panels.
Besides that, going into standby mode or even blanking the monitor sometimes freezes the desktop completely.
I am having huge issues with the new Unity interface, especially in combination with Google Chrome.
Different windows will not draw nor focus correctly, large portions of the screen become corrupted and the window buttons (close, minimize and maximize/restore) tend to disappear from the panel.
Sometimes the left panel refuses to slide back even though I have a maximized window in the foreground.
I am running standard Ubuntu 11.04, fully updated, with universe and multiverse repositories enabled.

I have attached a video of the buggy Unity interface and screen corruption with Google Chrome.
