Hi and thanks for using the library! Hope it's useful.

You can use the .setTextFormat() method to fix it:

var _textbox = new UITextBox("Test_Textbox", 80, 30, 150, 50, grey_button08); 
_textbox.setTextFormat("[fa_left][fa_top][c_black]").setPlaceholderText("Hello World"); 
_panel.add(_textbox);

Full code for example above:

var _panel = new UIPanel("Test", 40, 40, 300, 400, yellow_panel); 
_panel.setTitleFormat("[fa_center][fa_top][c_black]").setTitle("NEW GAME"); 
var _label = new  UIText("Test_SeedText", 30, 30, "[fa_left][fa_top][c_black]Seed: ");
_panel.add(_label);
var _textbox = new UITextBox("Test_Textbox", 80, 30, 150, 50, grey_button08);
_textbox.setTextFormat("[fa_left][fa_top][c_black]").setPlaceholderText("Hello World");
_panel.add(_textbox);
var _button = new UIButton("Test_Button", 0, -20, 280, 40, "Start game", yellow_button00, UI_RELATIVE_TO.BOTTOM_CENTER);
_button.setCallback(UI_EVENT.LEFT_RELEASE, function() {     show_message(UI.get("Test_Textbox").getText()); });
_panel.add(_button);

Let me know if there's anything else I can help with!
