I am using a Lenovo ThinkPad (T460s), 8GB RAM with SSD. I am suffering from the same problem. It seems that it is worsening when the number of slides is growing. There is one more problem as well, which I am not sure if it is correlated to the hanging problem, which is a confusing undo operation. When I try to undo some steps, most of the times I am not able to recover the previous status. It is happening even when there only two to three steps of undoing. I even increased the memory in the memory options, but it didn't change anything, just it made things worse.
I did have this problem with ubuntu 14.4 and the previous version of liber, however, I didn't have the hanging experience very often. -- 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/1584740 Title: Libreoffice impress hanging and high cpu on slide operations Status in libreoffice package in Ubuntu: Confirmed Bug description: Steps to reproduce: - Create a presentation in libreoffice impress, 30-100 slides with or without images - Add, copy or delete slides - On those operations LO Impress hangs a lot; sometimes 5 mins or more - Opening and saving works quick Tested on 2 different laptops, both had the same issue.
