Minisize firefox window causes corrupted screen when using fglrx driver

[lzy]

I am using fglrx 13.200.I upgrade my kubuntu to 13.10 recently,however fglrx is not working well as usual.
When I open firefox and minisize the window,the whole screen becomes corrupted(the screen becomes twisted,sometimes the screen just become black,however the mouse pointer can be shown as usual).Other Windows are not acting normally as well.When I maximize a window and then change it to normal size,the buttons in the titlebar will not be drawn until i move the mouse over them.
I am using kubuntu 13.10 amd64 and kernel 3.10.0-996
