erratic behavior in VI Display

[ttsesm]

When I try to use the VI Display to visualize the calculation results if I enable the Point visualization and browse around the model to see the values from different angle and distance these disappear or do not show up at all:

While doing this, the following errors mostly show up in the console:

Thanks for the bug report. That error is now fixed in git.

Hi Ryan,

I am still getting problems in this one.

This if I have calculated the result per vertices:

You can see also that the values are not showing up consistent:

And this per faces:

Here the numbers are not showing up at all:

I am still getting the error:

I've noticed though that it is showing up if I set both the terrain and the cube as Light sensor surfaces, if I set only one them then I am not getting any error message. I hope it helps.

Thanks for the bug report. Tougher nut to crack this one but should now be fixed in git.

[ttsesm]

I confirm.
