Main issue

</summary?
What is going on in my case using Paint (messy but works):

Edit: In the image, reverse the colors of the other boxes for the second and third row. I messed up painting them.
The issue I have is I have a slider for a hotbar, with all buttons put into a slider, with the parent of the slider with ClipsDescendants set to true. Even when the slider is moved and button clipping changes, they still can’t be selected (via a LocalScript or select button).
Is anything rotated? ClipsDescenants don’t work when it’s rotated.
I don’t rotate anything. This is a completely different issue.
My guess is it is based on how the math is done for selection dialogs seeing if a part is within a non-clipped area, but I am not sure.
Edit:
Ok, I believe it only calculates it’s parent. I made the buttons move instead of the slider, and it fixed the issue.
