Starting 2-3 months ago (I'm unsure when I first noticed the issue), I can no longer take decent videos with the GrapheneOS camera.
Videos are recorded with frame skips lasting about 1 second, every 10 seconds or so. The audio continues playing correctly, but the video "freezes" periodically when playing back the video.
The frame skips are visible when coping the videos to other devices, so it's not an issue with the gallery app.
I've tried reducing the quality to 720p and disabling image stabilization. This makes the frame skips less frequent, but they still occur.
This happens on my Pixel 7. Also occurs on a Pixel 8a which I just purchased, with a fresh install of GrapheneOS.
