Description:
Hello,

Since I updated to 5.3.6.1 or 5.4.2.2 my documents are very slow to view and
modifying.

Also the spellcheck functionality doesn't work any more in Calc: 
Impossible to select my language : French

I come back to 5.2.7 and all working fine now.

Anyway, congratulation for your great work. I love LibreOffice

Steps to Reproduce:
1. Install 5.3.6.1 or 5.4.2.2
2. Open a calc, writer or draw document 
3. scroll the document

Actual Results:  
Very slow, about 1 second to scroll an horizontal half screen of document.

Expected Results:
smoothly scrolling 


Reproducible: Always

User Profile Reset: Yes, even try to reinstall with clean up profile. Safe mode
is also very slow.

Additional Info:
I have tried on 2 Lenovo T420 Intel i5 core laptop. Windows 7 pro. Same result.
LibreOffice 5.2.7.2 is working fine.
