When I use the little planet effect in ptp 2.0 it appears with black corners and the movement is not as normal (jagged) as it was in ptp 1.8. The black corners appear in a 22in screen. In smaller screens there are no black corners but the problem with the movement is the same. You can see an example in this link: http://thomas360.dotsyntax.gr/little_pl ... error.html
Ok reproduced on the flash player on your visit. I'll add a report for this problem. Is it possible to send me informations about your file : width and height in pixels ? Or better, is it possible to send us your equirectangular, and your project file ? Thanks
Next release doesn't use same little planet parameters and it seems working. So problem is probably due to the limitview="lookat" value of the view during littleplanet effect into your RC1 build.
