Desktop Wallpaper Shows Through Videos in Pot Player

[jseidel]

I recently did the auto update to Pot Player 64 bit version 1.6.51480. Whatever desktop background I choose now shows through any video I play similar to a watermark. The design on the wallpaper shows faintly through the videos. Never had this before or anything like it. A setting I need to change or should I roll back to previous version?
My specs:
Cooler Master Elite 430
Asus P8Z68-V PRO/GEN3
Intel Core i5 2500K, 3.30 GHz
ADATA 8 GB DDR3
EVGA GTX 560 1GB PCIe
Sound Blaster Recon3D PCIe
1 TB Seagate Barracuda 7200 RPM
P/S: Corsair GS800
Windows 8.1 Pro 64 bit with Media Center

Thanks in advance.

Changed to a different skin, Metro X, and the transparency is gone.

Slide the transparency slider (it's next to the minimize icon) all the way to the right

This is how the top corner, including where the "transparency slider" looks with the Metro skin:

Maybe the transparency went away because the control isn't there?
Thanks,
