I can reproduce this on LibreOffice 5.2.7.2 with the file from comment 18 when I paste the contents of that file into a single cell. In fact the first time I attempted to paste, calc crashed and then it's document recovery dialog appeared. The paste worked on the second attempt, but was very slow. Attempting to edit the text in the cell was also very slow.
However this doesn't seem like a common use case for a spreadsheet. I would expect that text like this was stored and edited in a writer document. Do you mind if I ask why you want to put this large amount of text into a spreadsheet cell? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1034999 Title: libreoffice-calc very slow to open/save documents with large cell contents To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1034999/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
