Description sam 2018-10-30 04:10:37 UTC
Description:
I have a doc that is maybe 7 pages.  If I put my cursor in the middle of the 4rth page (the middle of the docuemnt), and scroll up and down through out the entire doc, the UI freezes when passing page 4.  It seems to freeze the UI when it starts having to render the cursor.  The is really bad because A user spends 98% of the time around the cursor, so scrolling is constantly glitching and skipping pages ahead and back as it unfreezes.  

Version: 6.0.6.2
Build ID: 1:6.0.6-0ubuntu0.18.04.1
CPU threads: 12; OS: Linux 4.15; UI render: default; VCL: gtk3; 
Locale: en-US (en_US.UTF-8); Calc: group


Steps to Reproduce:
1. make several page doc
2. put the cursor in the middle of the doc
3. scroll up and down around the area of the cursor, observe the glitchy behavior.  
4. Note how scrolling up and down is useless because the skipping makes you loose track of any line you where reading/looking at

Actual Results:
Scrolling up and down with the mouse or trackpad skips large leaps up and down and text re-render looks glitchy and unreadable.

Expected Results:
I would expect that the scrolling would be continuous and smooth enough to not loose my place on the pages I'm reading.  


Reproducible: Always
