I have this exact issue, and I really don't think it's google's fault. Both those sites are using canvas to draw charts. I experienced it on crypto trading sites mostly. Try a fresh profile, copy your bookmarks and history over to the new one. I did this and the problem was gone. (See my other comment in the thread)
