Snagit (Windows): Crashes or the crosshairs are sluggish when trying to take a capture.

Problem

The cross hairs freeze, are sluggish, or may crash when capturing the screen.

Solution

This behavior can be caused by having many monitors connected to your computer, or using multiple 4K monitors. Snagit currently supports using 2-3 monitors, or a single 4K monitor. However, there are some things that are worth trying before you begin disconnecting monitors.

Option 1: Enable Simple Cross Hairs

In Snagit 12 and later, it is possible to change the appearance of the cross hairs so that it is easier for them to render on the screen. In some cases, this can improve performance when multiple monitors are being used. 

Snagit 2018 and Later

  1. Open the main Snagit capture window.
  2. Click File > Capture Preferences.

  2. Select Personalize.
