First generation Garmin Mini Dashcam. Probably around 3-4 years old. SD card is original to when I bought it. I haven’t pulled any clips from it for awhile. Went to pull a clip of another driver doing a stupid, then found all my clips going back for the capacity of the SD card are having this weird visual issue. Seems to happen on/around white colored objects. Does anyone know what is broken?

Thanks.
