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

Question

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. See: I guess there could be some setting to switch it on, but don't know how.

Anybody can help, thanks!

Thanks & Regards, Martin.

Answer 1

I'm also facing the same issue and found the solution given below on Stack Overflow:

const ctx = canvas.getContext('2d', {willReadFrequently: true});

But it needs to change directly into cesium.js which is not possible from the developers end.
