Ubuntu 18.04.1操作系统，QT版本5.12
启动显示3D窗口的程序后，控制台将写入以下警告：

你在用QSurfaceFormat吗？我也遇到了同样的问题，取消注解QSurfaceFormat.setSamples有助于解决这个问题：

QSurfaceFormat fmt;
//fmt.setSamples(4);
fmt.setVersion(3, 0);
QSurfaceFormat::setDefaultFormat(fmt);

这对我很有效：export QT_XCB_GL_INTEGRATION=none
ps：有些人提到这可能会发生在remove desktop/vnc（在我的例子中，它是一个连接到aws ec2示例的vnc）。
