Calc loads fast (normal), but its response during “normal operation” is extremely slow. By “normal operation” I mean eg selecting columns, selecting cells, scrolling down, etc. in a medium (or even small)-sized spreadsheet.
For example, in a spreadsheet with 100 rows and 10 columns, it behaves really slow, as if it was dealing with thousands of rows and columns.
Writer shows similar behavior when navigating through a regular 10-pages ODT file (created with LO) with text, images, bookmarks, etc. nothing extraordinary.
The overall behavior of LO7 is much, much slower than previous versions for the same files.
I use latest light-weight Linux (Lubuntu 20.04) installed on SSD with a lare swap file and 8GB of RAM, so I don’t expect the problem comes from there (also, all the other software has no problems at all related to speed and memory)
I tried completely uninstalling LO and reinstalling. No changes.
What can I do next? I love LO and I am willing to do any other test you suggest to find the problem.
