在使用不同光学尺寸的字体时，我遇到了一个奇怪的问题。编译以下示例时（使用 lualatex 或 xetex）
\documentclass[10pt]{memoir}
\usepackage{fontspec}
%\setmainfont{Arno Pro}
\setmainfont{EB Garamond}

我在日志文件中收到以下消息
LaTeX Font Info: Font shape `EU2/EBGaramond(0)/m/sl' in size <10> not available
(Font) Font shape `EU2/EBGaramond(0)/m/it' tried instead on input line 100.
此错误总是出现在第二页的第二行（为了检查这一点，我插入了垂直空格来更改新页面的开始位置），并且当使用具有不同光学尺寸的字体时也会出现此错误。
对于 EB Garamond 来说，这不会造成太大问题，因为输出看起来应该如此。但是，当使用 Arno Pro（10pt）时，第二页第二行的斜体比应有的要大（因为使用了错误的尺寸）。以下是第二页的开头（使用 Arno Pro，10pt）
我正在使用的 pdf 阅读器（evince）告诉我使用的字体是 ArnoPro-SmTex、ArnoPro-ItalicSmTex（如预期的那样）和 ArnoPro-Italic（不应使用）。
有没有什么办法可以解决这个问题？
我正在使用 texlive。
