Explaination: When hovering any item or block that shows the tooltip going up instead of left/right, It proceeds to go through the screen instead of making a new line to make it easier to read the texts.

Expected behavior: https://i.imgur.com/eQQnaLy.png
Actual behavior: https://i.imgur.com/hNABA5u.png

Workaround (For now): Shrink the GUI size or maxmize the game window/Enable fullscreen to be able to read the full contents.

I've had a similar one as well - the tooltip just phases through the bottom of the screen for me.

Can you post the full screenshot instead of the cropped one?

And this is with the workaround i have tried. (Aka shrink GUI size + This is still 1920x1080)

The actual behavior when the GUI is too large for text to fit in with either maxmized window or normal size. (1920x1080)

Thank you for all the information! This seems like a tough one to fix. It looks impossible to fit without scaling the height of the tooltip window itself. I'll have to look into doing this

Ah that's a huge tooltip, I did not test with anything that large. What mods are you using so I can recreate that set to work out a fix

I have used tooltipfix mod and fabric-api with default window size, Then went to hypixel to try out the tooltips. ^

Update to this comment: Tried this on my own modpack and the actual behavior is still present.
