Video stuttering in Google Chrome with hardware acceleration enabled

I had same problem and the solution is go to System Preferences > Keyboard and uncheck turn keyboard backlight off. This will make Chrome work smoothly .

Video will be lagging and stuttering in GC if you've got many GC plugins, use hardware acceleration option (nowadays this option still has many bugs), got outdated graphics card drivers, etc.

To fix lagging/stuttering video, try this:

• Disable "Use hardware acceleration"
• Browse in "Incognito Mode"
• Delete cached files and cookies via "Clear Browsing Data..."
• Disable unused plugins under chrome://plugins
• Disable all extensions under chrome://extensions
• Update graphics card drivers (use the latest update in macOS)
• Use the default theme in Chrome
• Reset your browser settings

Also, try Chrome Canary to see if the issue still exists there. And look at this page as well.

Try using the resolution that is default for the display.

I had the same issue with HW acceleration, with the latest Chrome and Mac OS updates. Reverting the display resolution to default fixed the issue for me. However, this means it's an Apple bug.
