The Infuse control bar on macOS always jumps between glass and Gaussian blur effects, hoping to get this fixed.
Hmm, when are you seeing this change? Does this switch happen while playing a single video or does it appear different when launching different videos?
Have you adjusted the Liquid Glass settings in System Settings?
The control bar will automatically change when viewing certain segments of the video; this happens in all videos. My Mac display settings are set to clear.
