we just began experiencing this problem today. Chrome opens a white window with the _ and X visible in the top right corner. No tabs, address bar, etc.
I can position the cursor and click where the Chrome menu is supposed to be, and the menu appears.
If I resize the window, the new areas appear solid black.
I have uninstalled chrome manually, deleting the C:\program files (x86) directory, the appdata directory, and the registry keys.
Then I rebooted and reinstalled Chrome from chrome.google.com and still get the problem.
Any suggestions?
