I have a fresh installation of Windows 10 Pro (yesterday), a fresh installation of LibreOffice 220.127.116.11 (no customisations). I have a single document (.doc format) with 3 columns and two pages with one graphic and the rest text. Inserting or deleting a character takes seconds to show on screen. Converting it to an odt file had no effect on the speed.
The hardware is an MSI motherboard with a Ryzen 1600+ CPU and 16GB of RAM. Video is an nVidia GTX 750ti. The hard drive is a 1TB PCIe with a measured read speed of 3Gbs, so that can’t be the cause of the slowness. There is no other software installed, so this has to be a Writer problem.
On another computer using (ugh) Microsoft Word, there is no lagging. What can I do?
