1. have you tried this with any other sites?
2. if you have and it's happening on every site try clearing the cache of the chrome app
3. if this does not help try contacting Google support at: https://support.google.com/
Same for me. It's fine for a few minutes then it all turns black, chrome and chrome canary both do this for me. Oneplus 7 pro
I installed chrome beta and the problem seems to have been taken care of
