Safari Flickering

I don't know why my Safari is flickering. I also don't know if it is only for specific websites, but when it starts flickering, every opened tab believes the same.

Well, again I don't know whether it is only for Macbook Air M1 or any other kind of device. But yes, I haven't encountered any issues like this before and Safari is working well on my iPad.

Please let me know the process to overcome this particular issue as soon as possible.
