Macbook pro 16 inch 2019 noisy display in chrome after waking up from sleep I have this issue sometimes when my mac is waking up from sleep. Some applications like Google Chrome
A part or whole of the application is turning into a noise picture and until I restart the system, it won't fix.
In this screenshot I have opened inspect view of google chrome. In some websites, one part or whole of the website also, is being displayed like this.
I've updated to the latest version of Mac (Catalina 10.15.7) and chrome (86.0.4240.183 (Official Build) (x86_64)). Also this issue is happening when I use the main display or external display too. No differences.
This bug has been reported to the Chromium team since 06/04/2020.
Impacted Apps
This seems to affect all Chromium-based applications include Google Chrome, Brave, Electron, and probably others.
Symptoms
In my case it happens sometimes after sleep.
Cause
Chrome is saying its an Apple issue. Apple saying its an AMD issue.

29/01/2020: We're continuing to press this issue with Apple. They recently report that the bug has been reproduced and that AMD is investigating it.

There also appears to be some drama between Apple and Google in terms of whose problem it is.
Workarounds
Kill Chromium GPU Helper process (activity monitor)
This method is advantageous as it doesn't require restarting your browser and potentially losing your tabs.

Open Activity Monitor
Search for (GPU)

All Chromium-based apps including Electron apps will have one or more GPU helper processes. E.g. Spotify Helper (GPU), Code Helper (GPU), Google Chrome Helper (GPU).

Force Kill the GPU process of the offending app. NOTE: You may have to do this multiple times.
You should see the page go white, and then the green bars should no longer be visible.

NOTE: This doesn't always work, see the Chromium bug thread below for more information.
Thanks to: https://bugs.chromium.org/p/chromium/issues/detail?id=1068170#c188
Alternative: Use Terminal.app
An alternative to Activity Monitor is to use Terminal.app
killall &quot;Google Chrome Helper (GPU)&quot;

Disable Hardware Acceleration

Visit chrome://settings/system in the browser
