Description:
Print dialog is deeper than screen . Thus bottom is cut off . Print, delete, cancel buttons are invisible even when panel is removed

Steps to Reproduce:
1.Compose document in LibreOffice Writer
2.Select Print
3.Print dialog /diaglog sub-screen is deeper than screen, so no ability to click "print"
4 IF Writer document exported as PDF, the print dialog is smaller and printing can be done.
