Hello! Sorry if I'm missing something and this is completely obvious, but i can't seem to figure out the problem;

I am trying to make a button, using custom font and all, and i want to center it, but the bottom is always bigger than the top.

I have set the frame padding and the text align so the bug is more visable:
ImGui::PushStyleVar(ImGuiStyleVar_FramePadding, ImVec2(0, 0));
ImGui::PushStyleVar(ImGuiStyleVar_ButtonTextAlign, ImVec2(0.f, 0.f));

The problem is only there when i try to change the font to other ones, but there is no problem on the default one.

The fonts I am showing are: ST-SimpleSquare and Helvetica.
(i upscaled the def font in the photos so it is more visible)

!- maybe it is for the letters that have down hangers/cops like: j - y - q - g - p,
but still i must ask how to center it.

Nailed it! It is from letter with down hangers and cops.
