I made a Gui design with UICorner and ClipDescendants, but annoyingly, ClipDescendants seems to be off by 1 pixel, making my button look like this:
As you can see on the bottom, the 2 frames are not alligned properly
ClipDescendants off:
I COULD use 9slice, but it isnt scaled properly, so it would look weird on smaller devices:
My computer:
Phone:
As you can see, the X button has weird proportions
The temporary work-around it to just upload an image of the Gui, and NOT 9slice it.
For instance the green and black Gui is 500x400 pixels, so I uploaded a 500x400 pixel image of the Gui:
Same with the button:
