Resize OK but shadow is black border

I'm using phpAlbum on different servers.

The only difference for the gd lib I can see is:
On server1 - FreeType Version 2.1.9 - all is working well
On server2 - FreeType Version 2.2.1 - shadow issues

The issue is that the images seem to hae a black border (on the right and bottom) in stead of a shadow. I undertsand it's GD Lib that takes care of this. The resizing works however and I'm also using GD Lib for captcha on other parts of my site. Also the watermark seems to be ok. Is there any setting I need to take care of? (Must have done something wrong)
If you need phpinfo :

Thanks in advance.

I also have the same

I also have the same problem, but hosting in my local WAMP is fine!
When I click the thumb, the image go to full size page, but the shadow border on the bottom right seems not perfect match! showing a gap between the corner!
