Test failures with freetype 2.14.0 #286
Description
What doesn't work?
Running the automatic tests of py-sdl2 with the recently released freetype 2.14.0, some golden master test fail:
How To Reproduce
I reproduced the issue in conda-forge/pysdl2-feedstock#37, it can be easily reproduced by building py-sdl2 with conda-forge dependencies, I can provide an exact reproducer if useful.
Platform (if relevant):
- OS: Windows, macOS, Linux
- Python Version: 3.10-3.14
- SDL2 Version: 2.32.56
- Using pysdl2-dll: No, using all dependencies from conda-forge
Additional context
This is similar to #212 .
The exact failures are:
