Mayavi：Linux下的渲染（别名）很差

Question

我写了一些mayavi代码，用于在周末可视化Windows上的线条和图像。当我回到我的linux工作台时，我对运行相同的脚本感到非常失望。执行时间要慢很多（通​​过暂时禁用mayavi中的渲染来部分修复）并且输出是别名的。我跑了glmark2测试我的显卡没有问题。

我可以做些什么来在mayavi中获得更好的渲染效果？

Linux - 别名行：

Windows - 线条更平滑：

更新

我用Nvidia N450GTS显卡更新了我的系统，目前我正在使用专有的NVIDIA驱动程序（NVIDIA-Linux-x86_64-337.19.run）。输出仍然是严重别名，正如我后来发现的那样，包含不正确的z顺序元素，如下图所示：
