This could be an invalid test scenario for Windows: 8u does not support High DPI environment fully. It may be unable to correctly identify the resolution of image to be used as the splash screen or capture the screenshot.

It requires more investigation why it fails.

This failure is more intermittent in its nature, I found only a couple of failures like this one for 8u.
