FontRenderer.getStringWidth returns wrong width

[Johni0702]

Note: This is almost certainly the same as #396, however that thread suggests various causes/symptoms that I cannot reproduce and has been close half a year ago.

Summary

The default font renderer returns values from getStringWidth(String) that are smaller than expected for certain inputs using certain resource packs (with HD fonts).

Example

String text = "Login to ReplayMod.com"
FontRenderer fontRenderer = Minecraft.getMinecraft().fontRendererObj;

int width = fontRenderer.getStringWidth(text); // width is 100 but probably should be 101
fontRenderer.listFormattedStringToWidth(text, width);
// ^ expected ["Login to ReplayMod.com"] but is ["Login to", "ReplayMod.com"]
fontRenderer.listFormattedStringToWidth(text, width + 1);
// ^ as expected ["Login to ReplayMod.com"]

width = fontRenderer.getStringWidth("*"); // width is 4 but probably should be 5
fontRenderer.listFormattedStringToWidth("*", width + 1);
// ^ As expected ["*"]
fontRenderer.listFormattedStringToWidth("*", width);
// ^ Throws StackOverflowException

The given example works correctly with the default resource pack.

[Johni0702]

Yes, as mentioned, this only happens with some resource packs (those with HD fonts or possibly only a subset of those).
