Description Dmitry 2017-02-24 17:17:40 UTC
When during mouse scroll page break become visible it is repainted twice time per single mouse scroll. During repaint I see ow dashes are running from left to right. This process takes about 3 seconds.

Steps to Reproduce:
1. open libreoffice writer
2. insert page break by CTRL+ENTER
3. scroll mouse down, wait until page interval will become visible
Reboot does not help.
Also this happens when page Headers and Footers lines are becoming visible.

Actual Results:  
CPU load during repainting for several seconds.

Expected Results:
Quick repaint.

Reproducible: Always

User Profile Reset: No

I have downloaded and installed previous version (LibreOffice_5.2.5_Linux_x86-64_deb.tar.gz), does not have this 
bug. My video-card is "ATI Mobility Radeon HD5400".
