Safari 8.0.6 toolbar flickers on some pages on MacBook Pro (Retina, 15-inch, Early 2013) after upgrade to Yosemite!

OS X Yosemite (10.10.3)

MacBook Pro (Retina, 15-inch, Early 2013)

Processor: 2,4 GHz, Intel Core i7

Memory 8GB 1600 MHz DDR3

Graphics NVIDIA GeForce GT 650M 1024 MB

Safari Version 8.0.6 (10600.6.3)

After successful upgrade to Yosemite, I've noticed that transparent Toolbar/Favorites bar flickers annoyingly. On some sites, where graphics are dynamic/animated, while scrolling through the page, when its content gets under the Toolbar, Toolbar starts to change color with high frequency. It is very annoying, distracting and doesn't allow to stay on affected page.

Kindly indicate what is the issue and remedy.

It is worth to mention that there are no other problems with machine itself, all other apps are functioning without issues.

Kind regards
