Description sergey.rahmanov 2017-07-18 15:18:12 UTC
Description:
Scrolling freezes on every page break that is on the screen. Other pages (without a break between them) scroll normally.

Steps to Reproduce:
1.Open any document with page breaks.
2.Start to scroll pages.
3.Try to scroll pages with the break between them.

Actual Results:  
When the page break appears on the screen, I get degradation of perfomance (like low FPS in games), so scrolling may take much time.

Expected Results:
There shouldn't be lagging scroll, especially in small documents.


Reproducible: Always

User Profile Reset: Yes.

Additional Info:
It happened after upgrade from LibreOffice 5.2. My OS is LMDE 2.

It doesn't explain behavior of my version (5.3.4.2, amd64, Linux Mint Debian Edition 2, kernel 3.16, CPU threads: 4). Can it be OS-specific bug?

Might well be, because I cannot reproduce it either.

Just for completeness's sake, please copy and paste the information from Help - About to a comment.

Are you scrolling by clicking the scroll bar and dragging? Or mouse wheel? Or keyboard?
