Problem description: 
Using OSx 10.9.2,64 bit, if I have a libre Calc window open in the background and another LO window, Writer or Calc, open in the foreground and scroll the background window the background window will be corrupted with never ending copies of the entry that was just out of sight in the background window, i.e. if scrolling down then the lower row just out of sight at the bottom of the window will duplicate for ever as you scroll down. If scrolling up then the same thing happens with the row just out of sight at the top of the window.

Note: OSx will allow scrolling of a background window without selecting the window.

Steps to reproduce:
1. Open a LO Calc spreadsheet longer than one page.
2. Open any Calc or Writer document.
3. Move the document opened in step 2 to the side enough to partially view the spreadsheet opened in step 1.
4. Hover the mouse pointer over the doc. opened in step 1 and scroll that document and observe the corruption.

Note: Verified it still happens with LO 4.2.4.1.

Current behavior: As described above

Expected behavior: Should scroll without corruption.
