Green and black rendering artifacts in Chrome and Safari (2019 16" Macbook Pro)

Various websites are rendering with green and black artifacts on both Chrome and Safari. Sometimes this is fixed by a re-launch of Chrome or Safari and sometimes by a complete system restart. Turning off GPU rasterization in chrome://flags was correlated with an improvement in this rendering issue in Chrome for a short period of time but the issue persists and appears unpredictably.

Chrome Version 87.0.4280.141 (Official Build) (x86_64)

Safari Version 14.0.1 (16610.2.11.51.8)

MacOS Big Sur 11.0.1

OP here. On 9 FEB, I spoke to Apple support again after more issues. I did a full reinstallation with complete hard drive wipe as if I were setting up to sell the computer. Previously I had only done a reinstallation and not a complete hard drive wipe.

Have not had any issues in the month+ since then under similar use conditions.

Based on this, I suspect if your computer shipped with MacOS 11 (Catalina) and you upgraded to Big Sur, the solution may be a complete hard drive wipe, as fun as that sounds.

Im having this issue too (chrome/teams etc), and overall extremely poor performance doing seemingly day-to-day tasks. This computer seems flawed at its core, it cannot handle an external monitor.

Oh really? And you installed from fresh, no back ups OP? Can you provide a link to the article you followed or something on how to do the full reinstallation with complete hard drive wipe?

And also OP, you are getting no artefacts in Chrome? Despite the fact that daniel_condurachi says that he did the reinstall and nothing helped?

As a workaround, disabling "Use hardware acceleration when available" in chrome://settings/system and then re-launching Chrome will usually (always?) fix things without a reboot. However, this will obviously impact performance and is simply a workaround until the underlying bug is fixed by someone (8 months+ and counting....sigh....)
