A Qml color animation from one full opaque color to a non full opaque color haven't the expected behavior.
It seem's to go in the first time to an opaque color's version then go the real requested color. But on quick animation there is like a color "blinking" that's very not confortable for the user.
Please find here after a code to reproduce the bug.
Please find also a gif attached to this issue presenting the bug with a slow animation (1000ms). The gif is divided into 2 tests, the first with a dark background and the second with a light background. The bug doesn't seems to appear with a light background.
