Animated Texture Glitch

[autumn kettle]

The block I am placing in the video is a block of redstone. I don't know why it is doing that. The thing on the right is supposed to be a computer with a screensaver on the monitor (the same texture as the block of redstone) but it just turns out gray.
block.json:

"redstone_block": {
  "textures": "computer_screensaver_1"
}

terrain_texture.json:

"computer_screensaver_1": {
  "textures": "textures/blocks/computer_screensaver_1"
},
"redstone_block": {
  "textures": "textures/blocks/computer_screensaver_1"
}

flipbook_textures.json:

{
  "flipbook_texture": "textures/blocks/computer_screensaver_1",
  "atlas_tile": "computer_screensaver_1",
  "ticks_per_frame": 1
}

If you need any other files please let me know.

Woah, so you can put it in the monitor block?

yes, I want to make animated screensavers. So far I have just resorted to a still frame, but I really want the animation
