polygonal hotspot －－－problem？

Hi，
I created a high resolution flat panorama with a polygonal hotspot.
If you increase the magnification, the line will move and appear as if it trembles.
Is there a way to get rid of this?

Quellcode

<hotspot name="redline"
     	keep="true"
     	visible="true"
     	enabled="true"
     	handcursor="false"
     	alpha="1.0"
     	polyline="true"
     	fillcolor="0xFF0000"
     	fillalpha="0.5"
     	borderwidth="5.0"
     	bordercolor="0xFF0000"
     	borderalpha="0.5"
     	borderzoom="1.0"
     	borderhittest="false"
     	subdiv="true"
     	>
    	<point ath="-0.500" atv="-0.252" />
    	<point ath="0.500" atv="0.252" />
</hotspot>

Thank you.

Hi,

that looks like a numeric accuracy problem of the calculations on the GPU...
And it seems to be system/GPU specific, I was able to reproduce on iOS but not on my Windows system.
Will look for improvements.

As 'workaround' for the moment you could use a non-GPU drawn polygon by adding renderer="css3d" to the <hotspot>.

Best regards,
Klaus
