Texmaker High CPU Usage And Slow Typing On Ubuntu 9.04

Posted on Oct 29 2009 by Matthew Jakeman

I have been using Kile for a while for my LaTeX editing needs but after getting a new netbook (running Ubuntu 9.04 netbook remix), and not wanting to install the KDE libs I decided to switch back to texmaker.

I installed it and loaded up a document to start doing a bit of work in it and the typing was extremely slow. I also noticed that the CPU usage shot up whenever I was typing. I tried the same on my desktop with the same results.

I did a bit of searching and it appears this is a known bug.

The only workaround I can find is to use the following command to run texmaker.

texmaker -graphicssystem raster
This seems to work but isn’t ideal. I would quite like to know what actually causes this. Of course there is every possibility that this will be gone in 9.10. I will find out soon when I upgrade but the Ubuntu server traffic is ridiculous today with it being the release day so I think I’ll leave it a while before I do any upgrades.
