I have quite a big table. There is a lot of text i each cell. I observed that resizing the column or row with the mouse is extrem slow. Also maximizing the window back from minimized state is slow and give a black window for some seconds.
Using the same table with MS Excel 2016 cause no problems. The handling is fluent there.
I can observer the behaviour on Win10 with a quite Lenovo Yoga Laptop (Intel 4405U, 8GB RAM) and Debian GNU/LInux unstable on a desktop PC (2-core Intel-CPU with 8GB RAM). Of course on Debian I wasn’t able to test Excel.
Can you observe this behaviour, too. Are you aware of an open Issue/Bug report about that problem? I couldn’t find one.
As an example I used the first paragraph of Lorem ipsum as content for each cell of a AF
(columns) to 22
(rows) table.
