dronus, thank you for reporting this and helping make Ubuntu better. Could you please attach an example file that demonstrates the problem?
Also, as a WORKAROUND, one may see if one of the following PPAs alleviates the issue via https://launchpad.net/~libreoffice. ** Changed in: libreoffice (Ubuntu) Importance: Undecided => Low ** Changed in: libreoffice (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1531654 Title: Calc almost freezes on full table operations Status in libreoffice package in Ubuntu: Incomplete Bug description: When Calc as of Ubuntu 14.04 LTS is forced to do some calculation on complete columns or tables, it can take a very long time or freeze altogether, even if there is very little data in the table. For example, create a table with some number series about 1000 rows in some columns. Press Ctrl+A to select the whole table. Press 'Sort'. Calc does not respond to user interaction for a very long time now. If the used part of the table is selected by Shift+Ctrl+End instead, the sorting completes almost instantly. This problem may happen with many other operations too, and also triggers on full column selections (just click the column header) too. I think this is a mayor issue, as users can run into this in several ways (column- or full table selection, several operations) and may force them to force-quit Calc, loosing data.
