在 Linux 中构建下面的 MWE 时（Centos，TeXLive 2013，mdframed=1.9b，2013/07/01），我在正文中的红色圆角矩形内获得了淡黄色上的预期红色文本，在底部的 PGF 单节点图中获得了全黄色上的红色文本。[第一张图片]
在 Windows 7 (Cygwin、TeXLive 2014、mdframed=1.9b,2013/07/01) 中构建下面的 MWE 时，我得到了意外正文中红色圆角矩形内淡黄色底面为黑色文字，底部 PGF 单节点图中全黄色底面为红色文字。[第二张图片]
编辑：在所有情况下我都使用 xelatex。使用 luatex 和 pdflatex 我得到了黄色上的红色，正如期望和预期的那样。
当我修改 MWE （注释掉\usepackage[tikz]{mdframed}并取消注释）\usepackage{mdframed}时，我在正文中得到了红色文本，文本内部是淡黄色的红色非圆角矩形（正如我所料），在底部的 PGF 单节点图中，红色文本是全黄色的。[第三张图像；我认为由于 PDF 渲染而隐藏了顶部和左侧的线条 - 当我更改缩放级别时它们就在那里]
在 Windows/Cygwin 下使用 framemethod=tikz 时，它似乎忽略了 mdframed 中的 fontcolor 指令（并且font={c\color{red}，经过测试但未在 MWE 中显示；font={\sffamily}如 MWE 输出中所示执行预期操作）。
MWE 底部包含 TikZ 图片，用于验证 TikZ 颜色是否有效。此外，字体颜色在 mdframed 之外的其他地方（未显示）也可以使用。
为什么会发生这种情况？我该怎么办？

答案1
这似乎是介于mdframed和之间的错误xelatex，比我服务器上的更新。当我在服务器上更新 TeXLive 时，我得到了xelatex比以前更新的结果，并且得到了与xelatex我工作站上的结果一致的结果。（进一步的研究细节如上所示。）
从上面的评论来看，xelatex还存在我尚未遇到的其他问题。我切换到lualatex现在获得了预期的结果。
