Chromium based apps occasionally shatter (render blue noise) on MacOS Catalina 1 Recommended Answer 29 Replies 99 Upvotes

I have a MacBook Pro 16" running MacOS Catalina 10.15.4 (19E266) and this is what occasionally happens to me. Sometimes, seemingly after the laptop wakes up from sleep, all Chromium applications  (Chrome, Electron, ...) start having this ugly blue noise - surprisingly at the same time (not just one).

On the other hand it does not seem to be WebKit in general, since Safari is not affected by that.

Is it a known issue? Closing and reopening the Chrome does not help. I need to restart the computer.

I have exactly the same issue - only in Chrome browser and only after sleep.  Happened 3 or 4 times sometimes cleared with simple chrome restart but sometimes a power off reboot is the only way.   


Got this response from Apple discussion - not had a chance to try it yet

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
