我对 SDL2 比较陌生，但我为某些东西编写了一个快速而肮脏的程序。它在我的笔记本电脑上运行良好，但是当我连接到我的服务器并尝试使用 SSH 上的 X 隧道对其进行测试时，我瞬间看到了一个窗口的轮廓，然后出现以下错误：
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 130 (MIT-SHM)
Minor opcode of failed request: 1 (X_ShmAttach)
Serial number of failed request: 202
Current serial number in output stream: 203
其他 X 程序工作正常吗？甚至其他 SDL2 程序也是如此。
在网上查看，我得到的结果是OpenGL问题，但我的程序根本不使用OpenGL。或者，至少，它不应该，因为我的其他SDL2 程序运行良好，并且实际上并没有使用任何太复杂的东西，只是表面和位平面。无论如何，我尝试了这些解决方案，可惜没有任何效果......
有趣的是，当我通过 valgrind 运行它时，我得到了这个，并且不是上面的错误：
==29836== Warning: invalid file descriptor 1024 in syscall close()
==29836== Warning: invalid file descriptor 1025 in syscall close()
==29836== Warning: invalid file descriptor 1026 in syscall close()
==29836== Warning: invalid file descriptor 1027 in syscall close()

==29836== Warning: invalid file descriptor 1028 in syscall close()
==29836== Warning: invalid file descriptor 1029 in syscall close()
接下来是堆摘要，好像程序停止了，但它继续运行......然后过了一会儿，程序开始运行？当我关闭它时，它显示其他堆总结...
这是完整的日志，以防有帮助。

如果它有帮助的话，这是有问题的程序。
