Hi.

I've tried to find source of problem with black background in weather widget on events desktop. And I've found it in source code of libmeegotouch.
I've opened bug report https://harmattan-bugs.nokia.com/show_bug.cgi?id=759. And I attached my patch to this bugreport.
Also we can see at screenshot (see below) events desktop after fixing of this bug.
