Camtasia (Windows): Canvas Does Not Show Media That Is on Timeline

Problem

The canvas does not show the media and displays black, shows artifacts, or displays the desktop instead of the media on the timeline. 

Solution

  1. In Camtasia click on Edit > Preferences > Advanced.
  2. Under the section for Hardware Acceleration change the dropdown to Software Only Mode and then click OK.
  3. Close and re-open Camtasia and see if that works.
