Specific font size causes glitchy font display

[Xeaker]

When using font size 40 the text becomes weird. Font size 36 or 42 was fine.
I used the same font with same size in Java Libgdx and OpenOffice Writer and it looked fine there.

Other font sizes:

 bg = Sprite::create("messageBox.png");
 bg->setScale(0.0f);
 this->addChild(bg);

 TTFConfig ttfConfig("PixelHallfeticaJP10P-Regular.ttf", 40, GlyphCollection::DYNAMIC);   
 label = Label::createWithTTF(ttfConfig, "", TextHAlignment::LEFT, 1170);

 label->setDimensions(1170, 210);
 label->setLineBreakWithoutSpace(false);
 label->setLineHeight(70.0f);
 label->enableShadow(Color4B::BLACK, Size(3,-3), 0);
 label->setAnchorPoint(Vec2(0, 1));
 label->setOverflow(Label::Overflow::SHRINK);
 label->setPosition(Vec2(-600, 90));
 this->addChild(label);

It says I can't upload ttf fonts, I could upload in Discord, I used:
PixelHallfeticaJP10P-Regular.ttf

I use this if that matters

 glView->setDesignResolutionSize(designResolutionSize.width, designResolutionSize.height,ResolutionPolicy::EXACT_FIT);

When creating a new issue, there should be a template option named "Bug report", with some information you should fill out. It looks like this:

- axmol version:
- devices test on:
- developing environments
   - NDK version: r23c
   - Xcode version: 14.2+
   - Visual Studio: 
      - VS version: 2022 (17.9+)
      - MSVC version: 19.39+
      - Windows SDK version: 10.0.22621.0+
   - cmake version: 
Steps to Reproduce:

1. 
2.

Please always use the template when creating a bug report, since it reminds the poster to fill in some required info, such as the version of Axmol being used.

• axmol version: axmol version 2.11.2
• devices test on: Windows 10
• developing environments
  • NDK version: idk
  • Xcode version: idk
  • Visual Studio:
    • VS version: Microsoft Visual Studio Community 2022 (64-bit) - Version 17.14.7
    • MSVC version: idk
    • Windows SDK version: idk
  • cmake version: Is it that? cmake_minimum_required(VERSION 3.22...4.1)
    Steps to Reproduce:
    Maybe downloading the font file and use the code from the post will produce that error.
    If only I could upload .ttf here.

Here is a link but only works for 3 days

If certain file extensions are not allowed, then try archiving (with ZIP or such), and you may be able to attach that. You could also just create a repo in your own github account, upload a test project to it (or just the font), and link it in your post.

The corruption occurs at multiples of 10, so 10, 20, 30 etc. etc.. The reason seems to be that the PixelHallfeticaJP10P-Regular.ttf font file contains bitmap fonts for those sizes. It doesn't seem that Axmol handles the case of bitmap fonts embedded in TTF files.

You can see the bitmap fonts contained in it when loading in FontForge:

If you delete the bitmap fonts from the file, and save it back out, then not only does it fix the issue, but it also reduces the file size from 16MB to ~1.4MB. The file with the bitmap fonts removed is in this archive:

PixelHallfeticaJP10P-Regular.zip

Very nice. Thank you!
