test spreadsheet

In 5.1.0.3 scrolling through large spreadsheet is very slow and laggy. It's super smooth in 5.0.5.2. I'm using i5 2500K @ 4.2GHz & Win 8.1 x64. LibreOffice is also 64bit. Here are some comparison videos (watch them in 60fps):
LibreOffice 5.0.5.2 https://www.youtube.com/watch?v=EdhRSBqaDIk
LibreOffice 5.1.0.3 https://www.youtube.com/watch?v=9O8sUamtpX8
I attached this test spreadsheet.

Please test if disabling OpenGL change the situation.
Menu/Tools/Options/LibreOffice/View

It is so for me.

Interesting ! =) if the problem gets significantly better when you drop the text (ie. for a mostly empty sheet) - then this is a dup of bug#94682 - which Tomaz is working on. Could you test & if so, mark duplicate ?

Thanks !

Quick check suggests that the problems get significantly better without the text => marking as a dup of the already underway bug here.
