Problem:  Pasting a capture from Snagit into Microsoft Teams results in a blank image.  May also cause slow performance or failure of images load in Teams Notebooks

Solution:  This issue is caused by images that have transparency. To resolve this issue follow these steps:

Open Snagit Editor.

Browse to:

Snagit 2018 and later: Edit > Editor Preferences > Share tab > Clipboard.

Snagit 13: File > Editor Preferences > Share tab > Clipboard.

Check "Disable image transparency on clipboard."
