PDF 的问题，如 @u40 老师所说：

我的解决方案就是 pdf2ps SDUlogo.pdf epstopdf SDUlogo.ps 然后就OK了

或者 Inkscape / AI 重新导出，也能解决问题.

后记

我尝试了使用

gs -o <output.pdf> sDEVICE=pdfwrite <input.pdf>

以及

mutool clean -a -z -d -gggg <input.pdf> <output.pdf>

均无法修复，此问题可能涉及在以前 dvipdfm-x 程序导致 Inkscape 导出的 PDF 插入后使用 xelatex 编译透明度失效，后被 @马起园老师修复，但是又牵扯进来新的问题. 当然也不一定是这个问题导致的. 想要引擎层面彻底解决，需要比对处理前后的PDF，找出是什么导致了这个问题？并提交 Issue（前提是，如果是某段inputstream 导致，那只能硬着头皮提交了，把分析工作交给他们...）

在我更新过宏包版本的TL2025在windows上已经不能再复现上面的错误

因此最直接的解决方法就是tlmgr!

确认在frozen的TL2025上的xdvipdfmx会报错：

在macOS上的TL2025 frozen version仍然可以复现此问题：

xdvipdfmx --version
