Safari shows black box after clicking link

Since some time I notice a strange behavior with Safari on OSX 10.10.2 Yosemite, on a Retina MBP:

When I click a link to open in a new tab and then return to the original tab, then there is a black rectangle showing up around the clicked link.

Has anyone else noticed such a thing before?

Here I clicked a Google link:

Or this was on the Forum here:

It’s a graphics card thing. Does it go away if you scroll? (it should)

Have you ever launched a game and seen a jumbled display of what you were recently looking at in Safari?
It’s the same sort of thing.

No, I have no games on this machine.

This Macbook Pro is not even 3 years old and last year the ssd failed and now the graphics card starts to shake ? Arghh…
