Bug report with Avira.Spotlight.UI.Application.Messaging.exe white pixel appears upper left corner

Hi.

I would like to report a bug. When Avira.Spotlight.UI.Application.Messaging.exe is running there is a white pixel on the upper left side of Windows Desktop. The pixel disappears in the moment I taskkill Avira.Spotlight.UI.Application.Messaging.exe. I'm using Avira Free Security on Windows 10. have a look at the snapshot -->
