When calling ui::Button::setTitleText() repeatedly, memory usage continuously increases and is not released.
Steps to Reproduce:
in update(float dt):

    static int cout = 1;
    std::string title = fmt::format("{}", cout);
    _button->setTitleText(title);
    cout++;
    if(cout>1000){
        cout = 1;
    }

I create a empty project, and paste your sample code, but can't reproduce the issue

I run 44miutes, and memory usage remains stable at 224MB

Tested on MacOS?

I also check on macOS, not find any button setTitleText related leaks

@halx99, @NgVThangBz
Is there a full copy/paste code snippet for retesting?
=> also for doing the same things

@NgVThangBz
Can you run the test again using this code snippet?
Does the memory leak still occur with this?

@aismann see attachment: Source.zip

that not leak,
but in my code: i think it is memory leak

@halx99 @aismann please check it.
i not call: setTitleFontName
Is that the reason?

@NgVThangBz
I cant test it on MacOS:
With your code snippet
On windows there is no growing detected.
Maybe some other source in your app is the "offenders"
