I've just added LittleTiles_v1.5.0-pre199_64_mc1.12.2 with CreativeCore_v1.10.28_mc1.12.2. Now my screen will randomly shift hues to red for a random amount of time before returning to normal colorization. (This often repeats).

When this occurs all blocks with any opacity below 255 show as if they had 255.

Any other mods installed?

This is my modpack: https://drive.google.com/drive/folders/19DD3svJqxNJ97Ngdk4vThZFyoED7fHWV?usp=sharing

Here's also a side-by-side comparison of how it's affected

Is it bound to the block you hold in hand, or maybe caused by the block inspector?

Yes, sorry I have been busy. I am unsure about the block inspector, but it does occur regardless of the block in hand and including being empty handed.

I could not reproduce this issue. Are you 100% this is caused by LT? Maybe try and remove it again?

Still there?
