The interaction is laggy when turning on "DuckDuckGo Privacy Essentials"(Chrome extension)

This is the example project https://codesandbox.io/s/test-whiteboard-konva-sospee

You can see this when turning on "DuckDuckGo Privacy Essentials"(Chrome extension) and adjusting the rectangle size in that demo. The interaction is very laggy

DDG extension is monkey-patching ctx.getImageData() function with their own version. And it is very slow, compared to native function.

Relevant:

duckduckgo/duckduckgo-privacy-extension#574
duckduckgo/duckduckgo-privacy-extension#561
duckduckgo/duckduckgo-privacy-extension#560

I don't think I can do much from Konva side, so I am going to close the issue. If anyone have good idea what we can do here, please comment.
