Distortions on the desktop of target machine after Unattended runs

Good afternoon, colleagues!
At the moment, on several productive projects (Unattended Robot), a situation arises in which the machine on which the processes are launched, after several launches, starts to produce artifacts, bugs, as in the screenshot.
What could it be related to?

Hello,

Let me see if I get this right, after some robots run, unexpected files appear on the desktop?
I don’t know if I understood the issue.
