LXDE/Openbox下的不美观busy/loading动画

Unaesthetic busy/loading animation under LXDE / Openbox

我使用 Raspbian 和 LXDE 作为显示管理器设置了我的 Raspberry Pi。现在每当我启动一个应用程序时 this animation 会显示在屏幕的右上角。

有谁知道,是什么触发了这个动画,是否可以禁用它?

通常意味着你的电压不足。请参阅此论坛 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

如果我使用劣质电源或垃圾微型 USB 数据线,我通常会遇到这种情况。
