Fix qutebrowser high cpu usage

Published 2018-04-06 on Anjan's Homepage

I love qutebrowser for its vim keys but I found that qutebrowser's cpu usage was too high. Indeed, the cpu usage reached 80% on my sandy bridge i7 laptop when I had one archwiki tab open. To fix the high cpu usage, I disabled software rendering. Here are the steps I followed:

  1. Open qutebrowser
  2. Type in :set
  3. Look for qt.force_software_rendering and set the option to false
  4. Restart qutebrowser

Keep in mind that if you use Nouveau drivers you must have software rendering enabled and this fix will probably not work for you.
