Hello, Please try to disable openGL and HW acceleration. Tools - Options -View I remember these problems on ubuntu, but now I have ubuntu 15.10 and doesn't observe this. Probably it's fixed in newer version.
Alex: does comment 2 help? What Ubuntu version do you have? I guess 14.04? You can use this ppa to get the latest version: https://launchpad.net/~libreoffice/+archive/ubuntu/ppa Set to NEEDINFO. Change back to UNCONFIRMED after you have provided the information.
I am using Ubuntu 14.04. I upgraded mesa and my graphics drivers. I haven't noticed any problems recently. I consider this issue resolved for me.
