Shaky layer when autotour

Hello,

I'm experiencing a strange case where when the autotour starts, my hotspot layer becomes shaky.

The odd thing is that when I remove the parent relationship of my icon layer, it seems to stop the shakiness

What I have already tried, based on the messages I found on this forum :
- removing center alignment
- adding "accuracy=1" to my layers

Here's the code

<hotspot name="spot1field_double2" align="left" style="htspfield" ath="6.329" atv="16.251" onover="unwrap(spot1_double2, 150, Chambre dsouble);" onout="wrap(spot1_double2);" onclick="loadscene(scene_chambredouble2, null, MERGE, BLEND(0.5));"/>
<hotspot name="spot1_double2" align="left" style="htsp" ath="6.329" atv="16.251" padding="0 0 0 30" wordwrap="false" roundedge="15"  />
<layer name="icon" url="icons/p.png" align="left" x="7" width="15" height="prop" parent="hotspot[spot1_double2]" />

I have Krpano 1.20.7

Do you have any idea about this ?? Thank you !

Problem solved ! I used hotspots instead of layers and it works like a charm
