Unwanted Rainbow icon on pygame
<p>I'm currently working on a pygame script, which is basically displaying an user interface over a webcam stream. This app is running on raspberry pi, on dual screen via fbcp.</p>

<p>I noticed that a strange rainbow square icon did recently appeared in the upper right corner of the screen. </p>

<p>Looking like this, but smaller :

<p>What is it ? How can i remove the display of this icon ?</p>

<p>Thank you !</p>

<p>I found the answer by myself :</p>

<p>This icon is shown by the raspberry itself to inform about under-voltage issue.
To prevent it from showing, solve the power issue, or remove rpi warnings (not a safe approach), by adding to /boot/config.txt :</p>
