Is this a new issue you’ve run into after having it work properly before, or is this the first time you are doing this?
I haven’t used this resizing tool, but have you set the Scale, Anchor point, or size inthe GUI properties window first?
If you have you may have to set your Properties correctly to have it scale properly.
yea, ive noticed that scrolling frames in particular are terrible at resizing; they ALWAYS break. hopefully roblox will find a way to change this, as you cant really have scrolling frames with mobile support that way.
I fixed it! I just needed to set the scale to 1 for X and Y and then the offset to my desired value (as negative).
For anyone else coming upon this problem of GUIs resizing weirdly:
For position - Set position in offset.
For size - Set scale to 1 for both X and Y then, type the position you set in offset except as a negative number. This should fix the issue. If not, play around with it a bit.
