I’m using default tooltips for elements of my UserWidget. And it works fine while I’m in editor. But when I’m building a standalone distribution copy through frontend, tooltips won’t works at all.
UPD: more details were just investigated - no tooltips in fullscreen standalone build. In windowed mode it’s ok.
I then place that widget inside of a widget called “Holder”. In this example I have the widget constantly counting up so that it changes size as well as tracking the mouse.
