How to eliminate cesium warning Canvas2D: Multiple readback operations using getImageData are faster with the willReadFrequently attribute set to true

Hi Friends, I’m new to cesium, when i use this software, i always get warning in Chrome’s console: Canvas2D: Multiple readback operations using getImageData are faster with the willReadFrequently attribute set to true. I guess there could be some setting to switch it on, but don’t know how. Anybody can help, thanks! Thanks & Regards, Martin.
