Strange text showing when exiting game

[frank75]

Hi.

Did a fresh install of recalbox.
Now on 8.1.1with a raspberry pi 3.

After playing a few different games, i get this text as shown on the picture when exiting a game. Everything works fine.

And it popped up when i took Shut down system.
Then it stopped and I had to take out the power cable.

Anyone know what's causing this?

Thanks in advance.
