Opengl 如果我不使用外部监视器，我的JOGL会崩溃

这看起来很疯狂，但我已经能够重现一个问题，如果我不使用外部监视器，我的JOGL应用程序就会崩溃。我所做的就是启动应用程序，它会立即失去响应。如果我插入外部显示器，问题就会消失

如果我让应用程序运行，然后在调试器中随机暂停它，我会得到以下堆栈跟踪：

我还没有测试过是否可以用OpenGL重现这个问题

我做错什么了吗？也许我对显示器的问题感到困惑，这是另外一回事

您有没有可能在某个地方设置了vsyncenabledtrue或gl.setSwapInterval？如果您想了解更多信息，请搜索垂直回溯。

您正在运行-Djava.awt.headless=true吗？

您正在使用英特尔集成图形芯片组吗？我已经看到了一些关于JOGL支持多监视器或外部监视器的问题。您可以在另一台具有不同图形卡的计算机上尝试，以查看行为是否发生了变化-如果发生了变化，则您当前的图形驱动程序可能有故障。

Mmmm不，我认为我在任何地方都没有该调用。@Rosarch:可能值得显式设置其中一个或两个，你看到的问题很可能是没有监视器时没有垂直同步。Windows 7。JRE 1.6.0_21。
