As seen here on Normal GUI scale this tooltip window is placed in a very weird and far spot from the gui.

But there's no issue with [Auto] GUI scale.
Also [Auto] GUI scale is usually bigger than [Normal],I think.
Before the authors fix the issue,use [Auto] GUI scale to protect your eyes:)

So you mean this?
Normal:

Auto:

Yes. Also Auto is too big for me so I'm staying on Normal where it's a good size.

Thanks for the reports, Jared has fixed this issue by anchoring it to the side of the gui always. Unfortunately it will still look super weird when you have a high resolution, however this is an issue which affects all modded GUIs, like JEI. I will push a new beta to CurseForge for this in a moment.
