Animated hotspots are giving black squares for sprits bigger than 100px

Hello all,

I made this test example putting 3 animated hotspots, but its showing as black squares on chrome, messed animation on Edge

The results are the same even with on animation. I also tried the krpano pr12 version and gave me the same results

Is there a solution for this?
Thank you

Yep, looks like it.

I solved by making a square shaped srpite, and its working perfectly now.
