Hello, TheStarkiller. Thank you for posting to the Apple Support Communities. We understand the issue that you have been noticing when using your Mac and we can certainly help with this.
From what we understand, you are seeing new folders automatically created and saved to your desktop. We have several suggestions to help isolate this issue and rule out what could be causing this to happen.
To get started, we would first suggest that you start your Mac in safe mode. Using safe mode is an easy way to isolate out any software that may be generating these folders. While your Mac is in safe mode, please attempt to remove the folders and check to see if the same issue happens. The following Apple Support article explains how to use safe mode with your Mac:

If you notice the same issue in safe mode, we can help you more. To continue, can you tell us if you started to notice this happening after new software was installed or downloaded to your Mac?
We would also want to help you make sure that the latest system software has been installed to your Mac. The following article explains how you can update macOS for your Mac:

We hope that this information helps you and we look forward to your reply.
Have a great day!
