Java框架屏幕截图显示重新粉刷

我正在执行应用程序的jframe的屏幕截图，但通常会出现绘图伪影，例如在左上角的框架中的图像（不是通常的位置），因为我相信它在重新粉刷过程中抓住它。

有什么办法吗？我尝试在A Repaver（）希望它能保持完成后添加1/2秒延迟，但没有起作用（尽管出现问题的频率较低）。我认为合适的框架重新粉刷上有多个控件。我还设置了一个标志，以防止随时间延迟进行程序化重新粉刷，但是问题仍然蔓延。

我正在为屏幕截图使用以下代码：

BufferedImage img = new BufferedImage(this.getWidth(),this.getHeight(),BufferedImage.TYPE_INT_RGB);
this.paint(img.getGraphics());
File outputfile = new File(saveImageName);
ImageIO.write(img, ext, outputfile);

I'm performing screen shots of my app's JFrame, but often a drawing artefact shows up, such as an image in my frame in the upper-left corner (not where it normally is), because I believe it's catching it during a repaint.

Any way around this? I've tried adding a 1/2 second delay after a repaint() hoping it would stay finished, but didn't work (though problems occurred less often). I've got multiple controls on the frame repainting as they see fit. I've also set a flag to prevent programmatic repainting with the time delay, but problems still creep in.

I'm using the following code for the screenshot:

BufferedImage img = new BufferedImage(this.getWidth(),this.getHeight(),BufferedImage.TYPE_INT_RGB);
this.paint(img.getGraphics());
File outputfile = new File(saveImageName);
ImageIO.write(img, ext, outputfile);
