When testing a browser window using a bitmap check - the window and it's contents appears as expected, but TestPartner is failing. When we look at the difference viewer it has a 'double-vision' or shadowing effect such as below, but there does not appear to be any differences on this.

This issue is being caused by the zoom level on the browser. If the zoom was at 100% when the check was created, but has now been changed then this will be what is causing the issue. Change the zoom level back to the level that the check was created with, in this case 100% and the check will pass.
