Comment 4 for bug 577493

The window contents is there: when I type a new name and press enter for "rename sheet" dialog of oocalc, then the sheet gets renamed.
The dialog looks like what i often see from frozen GUI apps: when you switch to an other window and back, the screen area of this dialog window does not get updated, so you still see a fractions of the old screen contents (showing portions of the recently seen other app window).
Attached another screenshot.
