Description tjm 2016-09-02 17:30:14 UTC 
User-Agent:       Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.106 Safari/537.36
Build Identifier: LibreOffice 5.2.0.4

Calc starts fine but performance is very slow during loading a .csv or .ods file and also very sluggish after loading the file and during any manipulation at all, including scrolling vertically or horzontally.  Loading the same exact files in v5.1.0.3 does not produce this sluggish effect.  Tried different character sets with no change.  Remove column one at a time and found no difference in speed.  I can send a steriized copy of this file for examination.

Reproducible: Always

Steps to Reproduce:
1.Load file
2.
3.
Actual Results:  
Sluggish performance in 5.2.0.4 but normal in 5.1.0.3.
Scrolling just a few lines causes the lines to scroll at a rate of about 1 line/sec so scrolling a page of data could take over 30 seconds.  No delay takes place when using v5.1.0.3.

Just a guess: Nvidia graphics card and proprietary driver? Then this likely will be fixed with 5.2.1

If so, then duplicate of bug 101213
Comment 4 tjm 2016-09-12 16:14:06 UTC 
Downloaded and installed v5.2.1.2 and found the problem appears to have been resolved.  The offending file posted above loads, displays and can be manipulated normally and without any display delays.  Thanks.
