I just had an issue crop up where any movement in my cameras show up as pixelation. I have been running this system for about a year and this is recently started happening (I have 2 cameras connected). I'm running version 5.7.9.12, the PC has an Intel i7-9700 CPU with 32GB of ram and a WD Purple drive for storage with a Samsung 970 EVO 1TB drive for the OS. Any ideas?
