问题描述
我有一个Panel和一个jpg BackgroundImage(带有BackgroundImageLayout = Stretch).在面板上是Controls，我添加了带有的PictureBoxes，该PNG具有透明的边框.显示此内容不会带来任何问题，但是移动PictureBoxes确实可以.(移动框是可拖动的).
I've got a Panel with a jpg BackgroundImage (with BackgroundImageLayout = Stretch).On the panel it's Controls I add some PictureBoxes with a PNG which has transparent borders. Displaying this doesn't give any problems, but moving (the boxes are draggable) the PictureBoxes does.
结果是移动的PictureBox干扰" BackgroundImage并降低了性能.我拖动框的速度越快，对BackgroundImage的干扰就越大，反之亦然.
The result is that the moving PictureBox "disturbs" the BackgroundImage and slows down performance. The faster I drag the box, the more it disturbs the BackgroundImage, and vice versa.
如何解决这个问题?
