Does anyone know what this is/what it does, and which mod it cames from?

Context:
The small icon is always present, regardless of the dimension or game mode.
I updated my modpack and added a lot of content; it has been there ever since.
This means it can only be caused by the following mods:
– Better Advanced Tooltips
– Better Beacons
– Bosses'Rise
– Cherry Samurai Temple
– CreateBetterFps
– Diagonal Blocks
– Diagonal Fences
– Diagonal Walls
– Diagonal Windows
– Fast Paintings
– Genshin Instruments
– Kotlin For Forge
– Ocean Lily Pad Village
– Universal Sawmill

If it's not coming from any of these mods, then here is the link to CurseForge. The complete mod list is there.
