There are rendering artifacts when drawing one billboard or polyline in multiple frustums.

To fill in the back story, this is a known issue for billboards caused by the depth plane and multiple frustums, but now it is more prominent with the polyline.

I do see an issue with a polyline appearing in front of a mountain where it should be hidden behind. Could this be related to this issue / Is it an other known issue / should I create a new issue ?
Thanks for your help.

@vicb that is the same issue I believe. The depth values for the mountains are cleared so the polyline doesn't know that it is behind it.

I believe this is a duplicate with #1506. You can see below that the billboard is drawn when only the commands from the last frustum are executed. When the next frustum's commands are executed, you get the same image as above where the terrain overwrites the part of the billboard drawn over the background color.
I'm closing this because the other bug has more information.
