I had this problem today - I woke my computer (MacBook Pro 16" 2019) from sleep and I saw this:

![Chrome browser window displaying severe visual corruption with blue and green distorted lines covering the webpage content](https://flaviocopes.com/images/how-to-fix-chrome-rendering-issue/Screen_Shot_2020-05-17_at_08.23.jpg)

Weird, right? 

I reloaded the page - same thing.

I remembered I had the same problem a few weeks ago.

Back then I rebooted, and the problem went away. But I don't like rebooting. If I can, I go months without rebooting.

So I tried closing Chrome - no fix.

I also noticed the problem manifested on an [Electron](https://flaviocopes.com/electron/) based app, Workflowy.

But it didn't happen for all Chrome tabs.

So I tweeted the problem, and a kind random Internet person told me to disable hardware acceleration in the Chrome settings.

So I went and found the "Use hardware acceleration when available" option and I disabled it, restarted chrome, and the problem went away:

I then re-enabled that, until the next time I'll see this problem.

Hardware acceleration exists for a reason, and that's to make browsing faster, since Chrome can take advantage of the powerful GPU to render animations, for example, and to enable WebGL.

[It has been reported](https://support.google.com/chrome/thread/38267024?hl=en) through the Google Support channels but so far no fix.
