Tested with: fabric-api-0.30.3+1.16 | spatialharvesters_fabric_1.16.x-0.11.6a
Here are the screenshots for all GUI scales from 1 to 4 and F3 screen for system information. Also, I am not sure if this matters, but my monitor is an old 4:3 ratio one, not 16:9/16:10.

I think someone had a similar issue a while back with the Forge version. The fix was to use a later version of Forge itself where they'd added wrapping to long tooltips. Here's a Fabric mod that does the same: Mod

I'll close this since it's essentially fixed by that. I'll also pin it since it's a pretty noticeable effect.
