I set up my Raspberry Pi with Raspbian and LXDE as display manager. Now whenever I start an application this animation is shown in the top right corner of the screen.
Does anybody know, what triggers this animation and if it can be disabled?
Usually means that you're short of voltage. See this forum post Under-voltage warnings.
The B+ has an under voltage detect trigger which results in the power led going off when voltage drops below about 4.65V. The signal is also available on a gpio line (GPIO35). Latest firmware update will display a warning symbol in top right of display when this is detected. It will also disable turbo mode while the warning is displayed to try to reduce the chances of crashing. I've also added a warning symbol to the existing over-temperature condition (> 85'C), which also disabled turbo mode. Currently the symbols are: - Red square: over-temperature - Rainbow square: under-voltage
Typically I get it if I'm using a poor quality power supply or a rubbish micro USB cable.
