Mouse hover hide/show background video causing video to glitch

I created mouse hover animations for hiding and showing a background video. However, when I have the video at 100% width and height, it becomes glitchy and the opacity becomes less as well. When I have the video set to 70% width and height, there’s no video issues.

Is there a way to fix this because I’d really like the video to span the entire background in the section.

The work “hawaii” has the video set to 70% and works well. All other words: intuitive, impactful and innovative have videos set to 100% and have the glitching problem.
