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.

  • Boot into Safe Mode, does it still happen? Honestly that looks like (potentially) a hardware issue. Something in the video subsystem (video "card," cabling, etc) is failing. But it would be best to troubleshoot this issue as software first. Like Safe Mode, updating apps and/or the OS, possibly even wiping the drive and installing macOS from scratch. – Steve Chambers Nov 10 '20 at 14:20
  • Actually this happened only few times. and I don't know exactly what should happen to be occurred. But I know those times that it happened, was after waking up from sleep. – Ahmad Behzadi Nov 11 '20 at 22:46
  • I've updated Google Chrome and my Mac OS, as I had pointed in my question. Is not possible for me to re install the OS again, for now. I'm not sure if Mac has any possibility to reinstall graphic card drivers or not! Note that this issue was started after I've upgraded to Catalina Mac OS – Ahmad Behzadi Nov 11 '20 at 22:51
