Issu with background image/color get darker and alpha channel

Anonymous created an issue

Hi, While making my beamer presentation, I noticed that my background image (a png) get darker when: * an image is included * block are used with shadow I observed the same problem with a gradient instead of the background image.

After some investigations, I found that adding an alpha channel to my image fixed the problem with block. Also, adding an alpha channel to the included image helps.

I don't think this is a bug, but maybe it would be nice to tell about this issue into the documentation. Also, maybe a warning message at compile time could help.

I use beamer since years and it's a great tool: thanks a lot.
