webp screenshots cause video playback to lag and desync from audio

[QuestioningEspecialy]

Describe the bug
When screenshots are set to webp instead of jpg, the video ends up freezing consistently as the audio continues on. Though the screenshots continue as intended, they lag behind the audio and yet are well ahead of the video. 🤷🏿‍♂️
So I'm left to scroll down the folder as the screenshots are taken so I can know when to end it instead of being able to just watch the video like I always have before.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Options' > 'Preferences' > 'General' tab > 'Screenshots' section > 'Format': webp > 'OK'
2. Press 'Shift+D' > 'Spacebar'
3. bear witness

Expected behavior
Screenshots get taken without any lag or desyncing.
