So you use Virtualisierung Box?

You mean Oracle VM VirtualBox? Yes, but it was not running when the screenshots were made.

So you do not use deepin as a guest system. Alright- What is your graphic cards name and do you use a propeterary driver allready?

Well' What happens if you use the clipboard. Press PRINT open up a grphic software like gimp and press CTRL+V If that works this is a bug in deepin screenshot that should be reported trough the feedback app. If you got a black screen with the approach descrpted it may be a driver problem

I opened Deepin Screenshot and the whole screen went black. Only the cursor and the text of Deepin screenshot was visible. Like if you want to take a photo with your camera but you forgot to remove the lens cover. If i try this with GNOME screenshot, the 'foreground' is not visible, but it's there, because the result will be the same.

I see your point. But to be shure that this is a bug in the screenshot app you have to

1. Install gimp or an other image software
2. Press  The PRINT Key to send a copy of your screeen to the Systems Clipboard
3. Open The Graphic program you have installed
4.Create a new file
5. Press CTRL+V to insert your Clipboards content.
If the Image is visible like you expect it it is a softwre bug

If you got the same result as shown above this may be a graphic driver issue.

TTry this and show us the result,

1. Deepin Screenshot wants to save the screenshot to a file by default. How can i change it?
2. Result with GNOME Screenshot can be seen below
3. I'll install a completely different desktop environment like KDE or GNOME Shell on Wayland (maybe tomorrow or the day after tomorrow) to make sure this isn't a DDE-related bug.

I've installed KDE and (as you can see) have successfully taken a screenshot using Deepin Screenshot on it. So it's not the bug of Deepin Screenshot neither a driver issue. Weird.
