This never happened with previous releases. I have not seen any pattern about when this problem happens, and thus I do not know how it could be reproduced. The only way to correct this issue is restart of desktop, but if you are in middle of some important work, this restart may not be feasible. I have attached screen shot of my corrupted desktop.
