Question

我无法弄清楚我得到的这个错误：

X Error: BadMatch (invalid parameter attributes) 8
Major opcode: 62 (X_CopyArea)
Resource id:  0x4e00004

我想在一个应用程序的两个监视器上显示两个小部件。我使用以下屏幕配置（单个桌面，多个监视器）配置了我的目标： Screenshot

奇怪的是它适用于Suse下的旧X-Server。在Ubuntu下它没有。

以下是源代码和X-Versions

顺便说一下：
我必须使用这个配置（两个屏幕上必须没有虚拟桌面），我只是想了解它为什么不起作用。 - 相同的dirver - 所以qt-bug？

#include <qapplication.h>
#include <qwidget.h>
#include <qdesktopwidget.h>

int
main(int argc, char *argv[])
{
  QApplication app(argc, argv);
  QWidget widgetScreenZero(qApp->desktop()->screen(0));
  QWidget widgetScreenOne(qApp->desktop()->screen(1));
  widgetScreenZero.setStyleSheet("background-image: url(:/images/zero.svg);");l
  widgetScreenOne.setStyleSheet("background-image: url(:/images/one.svg);");
  widgetScreenOne.show();
  widgetScreenZero.show();
  return app.exec();
}
