It seems to me that in beamer, a (rounded) box with shadows that is covered (transparent, normally visible on the next slide) has buggy shadows, I'm not sure if this is a know bug, or maybe an error on my part.

My minimal code is the following



As you can see, the shadow seems to be above the box. It looks like this both in Acrobat Pro, Reader, and on Ubuntu.

Any ideas how I can get rid of it?

It looks fine in Mac OS Preview. Either it's a viewer-specific problem, or you should make sure that your LaTeX distribution is up to date. – Jubobs Apr 30 '13 at 10:00
I'm running pdfTeX 3.1415926-1.40.10-2.2 (TeX Live 2009/Debian) on Ubuntu/Lucid with evince 2.30.3 and it looks fine to me, as Jubobs suggested maybe you're running an older version? – Bristol Apr 30 '13 at 10:17
It was indeed a version issue, only beamer version 3.18 installed on this computer I am using at the moment. With beamer 3.26 everything works fine, Thanks. – Bernhard Apr 30 '13 at 13:20
On that basis, 'too localized'. – Joseph Wright May 2 '13 at 7:06
