Description: Hi, when I hide all columns and only use a few columns to have a cleaner view, the scrolling becomes very slow. Steps to Reproduce: 1. Open the Calc file. 2. Hide all columns and only keep some of them visible. 3. Do scrolling Actual Results: The Scroll becomes slow. Expected Results: The scroll should be fast. In Microsoft Excel works. Reproducible: Always User Profile Reset: Yes Additional Info: None
Have you enabled? Menu/Tools/Options/LibreOffice calc/Default/Enable very large spreadsheets. Please can you paste the information in Menu/Help/About LibreOffice, there is an icon to copy.
I haven't the check "Enable very large spreadsheets" option in version 7.4.7.2. I can't enable it. I don't understand where you want me to paste the information. Thanks you
I guess that the only way to reproduce this is with a file. Additionally, version 7.4.7.2 will not receive additional Community updates. (In reply to Gabro from comment #2) > I don't understand where you want me to paste the information. Open LO > Menu Help > About; there is an icon to copy the info to the clipboard. Come back to the report and paste the info in a new comment. I would first suggest testing with a newer version (or with a Development version installed in parallel).
I added additional information to reproduce the case. 1. First, open a new file in Calc and select, for example, the "G" column. 2. Then, press Ctrl+Shift and the right arrow key to select all columns to the right. 3. Right-click on the header of the "G" column and choose "Hide Columns". All of them will be hidden. At this moment, you can scroll and observe that it works more slowly than before.

The STR in comment 4 are easy-enough to follow. With _different_ scrolling rates in each version (i.e. other factors could be in place for each version), it could be reproduced since LO 3.3 and up to current Dev 24.2. OTOH, with the same STR, we cannot really be sure that the performance reduction is originated by _hiding_ (so many) columns, or by applying some/any attribute to such a big area. IOW, is _hiding_ the problem? Or is it the "huge" range of "active" cells? Further investigations would be needed. There are probably similar reports open already; let's set to NEW for now.
