Alpine Linux ships with musl libc, would it be possible for you to test with glibc? As well, could you provide the steps you used to build cimgui, Inochi2D and Inochi Creator?

[knuxify]

would it be possible for you to test with glibc?

there's no glibc in alpine, so not really

could you provide the steps you used to build cimgui, Inochi2D and Inochi Creator?

cimgui:

    cmake -B build \
        -DCMAKE_INSTALL_PREFIX=/usr/lib \
        -DBUILD_SHARED_LIBS=True \
        -DCMAKE_BUILD_TYPE=None \
        -DCIMGUI_TEST=yes \
        -DIMGUI_FREETYPE=yes \
        $CMAKE_CROSSOPTS .
    cmake --build build
    cmake --install build

inochi-creator:

    export DFLAGS="-O"
    dub add gitver
    dub build inochi-creator

i didn't build inochi2d myself, just used what was pulled automatically by dub.

Dependency versions pulled by inochi-creator:

Adding dependency gitver ~>1.0.0

...i now realized that i forgot to mention that i had to edit the dub.sdl file to change the bindbc-imgui version to 0.6.1 (which also seems to match the version here?), since 1.0.0 was seemingly unavailable - i could be missing something

[LunaTheFoxgirl]

Currently since everything is developing rapidly we clone inochi2d, bindbc-imgui, etc. from git, then run dub add-local . "1.0.0" in those folders to allow for that rapid iteration.

Library versions will be more stable closer to 1.0

[LunaTheFoxgirl]

Would it be possible for you to install the Flatpak package from flathub and see if the issue persists there? We've changed how font handling works so you can also try compiling Inochi Creator again.

[knuxify]

Flatpak works fine. The Alpine compilation attempt was more of an experiment; I currently don't have the time to work on re-compiling it (tried a while back and got some compilation errors I couldn't solve), but I'll treat this issue as fixed.
