I am using openlayers v 7.4.0 when I refresh the page this warning occur :
the Canvas2D: Multiple readback operations using getImageData are faster with the willReadFrequently attribute set to true. See:

** const L = h.getImageData(0, 0, a, a).data; **
this line off code had error but still work
if I did something wrong , let me know or please fix this .

Nothing to worry about. This ist just a hint created by the dev tools. But we tried to get rid of these warnings a while ago. So if you can tell us when this happens, we might be able to make it go away.

To me occurs when setting the style of a feature after getting it from 'pointermove' event.

Same version: 7.4.0.
