I'm currently using the resourcepack Catppuccin, for GUI. I'd like to edit/update it to get rid of the black line at the bottom of the hotbar selection texture. Using the screen safety area feature set to 3px.

The texture is a 22x21 image:

Can someone please help me fix this? <3

This is how it's supposed to look like: (note that the black line would not be visible, because vanilla doesn't have screen safe area)

If an tranasparent 1x1 image is used as hotbar_selection.png, the line stays:

Aditionally, a fix could be to create an options toggle of disabling the slot highlight texture being enlarged.

Hello! I've added a new option on "screen safe area" settings that disables this line. You can find the option as "Show Hotbar Selector overhang:" and set it to false.

This will be included in a future bedrockify version, hopefully to release soon.
