Hotspot disappears only when changing panorama

Hello.
I have been having trouble for some time now.

While blending the panorama, Nadia disappears.
You can check it by looking below the panorama and pressing the thumbnail.
What should I do?

Sorry for my bad English.

	<hotspot name="nadirlogo" keep="true"
	         type="text"
	         ath="0"
	         atv="90"
	         distorted="true"
	         width="300" height="300" bgroundedge="300"
	         scale="1"
	         bgcolor="0x2D3E50"
	         rotate="0.0"
	         enabled="false"
			 blending="true"
	         isblending=""
	         blendmode=""
	         />

Hi,

add renderer="webgl" to the <hotspot>.

Textfield hotspots are using a CSS3D renderer by default and the blending possibilities are limited with that.

Best regards,
Klaus

Thank you. klaus.krpano -san
