That's not how it looks on me, it is so random, sometimes it fade completely, sometimes not.https://www.youtube.com/watch?v=KGXre9FlDKQ
Notice that the movement is the same, so it has the same duration whever it is called.
fading lifetime is set to 5, in and out
movement speed is constantly at 139
other objects (text) are moved along with the graphic's x and y
The text is drawn in a surface, so the fade effect can be played, however, it doesn't have the issue it seems ...
For a menu this is not a problem, but for in-game entities like npc or else, this could be problematic
