Snagit (Windows): Image captures are white, black, or contain fragments of multiple windows

Problem

When initiating a capture, the entire screen turns black and only the cross hairs are visible. Or, the resulting capture is blank in the Editor.

Solution

This problem happens for all captures and is not related to hardware acceleration like image or video capture from a video. If all applications are closed and you capture only the desktop with any input set, this problem still occurs. Turning hardware acceleration on or off will not solve this issue.

The issue is related to security software blocking screen capture. We have identified that the following applications can cause problems with capturing the screen with Snagit,  however other security software may cause the same issue:

  • Webroot (Identity protection module)
  • Norton's CrimeWare
  • Trusteer Rapport
  • Zone Alarm, Zonealarm Forcefield
  • Kaspersky
  • Anti-Key Logger by SpyDex
  • Trend Micro

Most of these applications have a Safe or White list that Snagit can be added to. Norton's CrimeWare, however, does not have an editable safe list like other protection software and must be closed for Snagit to capture an image.

WEBROOT

With Webroot, we have noticed the screen go black after you initiate a capture with certain windows open.  This is related to the Webroot Identity protection module.  If you turn this off your capture should work.

  1. Go to Identity Protection settings:
