Hi,
it's a Safari bug - it's related to the webgl-shader used for the pano-blending - somehow it has an influence into the Safari internal video processing. After some time the internal memory of Safari gets corrupted.
The next krpano version will contain a workaround for that.
Best regards,
Klaus
Thank you for your full answer!
When do you plan to release the next release of Krpano?
Regards!
