Excessive Data Read by WallpaperVideoExtension

[labyrinth153]

I’ve recently noticed that the process WallpaperVideoExtension read 1.22TB of data over time. It seems like this could be a bug.

Has anyone else experienced this? Any insights would be appreciated.

Same here 1.36 TB on a MacBook Pro 14 M1, I changed background to a photo, let's see

What's the bitrate of the video that plays as a wallpaper? It's not like you can store it all in memory, so it will read what it needs, decode and display it, and then discard it from memory and load the next part from disk.

For sure, but that seems like excessive reads for a “wallpaper” feature, so I disabled it. It also could just be a bug and maybe Apple missed that it caused this much I/O

It all depends on how long it took to get to 1.22TB. 4k video takes quite a bit of space.

I noticed this as well, it averages at 8 MB/s. It's just always reading even though the wallpaper video is paused when I'm using the Mac, it's probably a bug. Not hugely concerning right now as reading doesn't wear out SSD.
