There is a notification that repeatedly appears for a fraction of second and then immediately disappears. I was never able to have a look at it despite many attempts. The only thing I was able to see is this notification icon 
which I captured with a screen recorder app and cropped to 32x32.
Google and Bing image search finds nothing.
Maybe there is a lossless screen recorder app so that I can capture it without artifacts? Or some kind of app icon database which allows for searches like this?
How can I deduce/identify an app from a notification icon? does not work for me because I am actually never fast enough to actually look at the notification.
