Hi,

Yes, I confirm for 1.16 pre-release 8. Some block drops are black for a moment while insta-mining. I found the result with sand and gravel with a shovel efficiency 5. It is very brief so I took a lot of screenshots to capture the issue.

I personally noticed this for the first time since 1.15.2 so it may be linked with MC-167359 (which has been resolved recently).

Hi it is me again. So I bought a new laptop (Dell G3 3590) with way better specs than the one I used before, and unfortunately the problem persists. I confirm for latest snapshot 20w21a.
To see the issue, dig in survival in total darkness to the deep underground. 

I couldn't capture the issue in the screenshot, but here are my specs:

Best wishes,

I confirm what people said above and that it affects 20W17A as well.

I just found a let’s play where issue is visible at 8:22

This issue is happening to me as well (1.15.2) everytime I play and mine. It is quite irritating so I am switching back my world to 1.14.4.
