Bug: Square cursor color on playground become darker as time proceeds on Xcode7.3

[pebble8888]

Description

On playground file, normal mode square cursor become darker as time proceeds.
At the end it becomes completely black and you can't read a letter on cursor.

It's OK for Xcode 7.2.1 and NG for Xcode7.3.
My patch (038e508) fixed the issue partially.
That patch has another bug.
When you use set blinkcusor, the cursor doesn't blink.

I investigated the issue. But I can't fixed it.

Does this still occur in Xcode 7.3 from the App Store?
