Let me preface this by saying that, considering its ability to play ALL of my local media files, the Boxee Box has already exceeded my expectations. Now that I have all my local content just the way I like it, I've started branching out and exploring some of the content available online and have noticed a bug that comes up relatively frequently.
When viewing flash video on websites that have other flash ads on the page, I sometimes find that, when I fullscreen the video, ads further down somehow start overlaying the content. This goes away when I turn off fullscreen. Something similar, but slightly different, also occurs when I watch Fancast videos (e.g. Conan). Here, a little triangle and line (like the seek arrow) overlays itself to the fullscreen. Not huge, but pretty distracting on a white background.
Anyone else seeing these?
