We have some odd behaviour when using aerial texture masks (CGL)... We are seeing large areas of white when far away from the target area. The zoom level was set to 19 when generating the tiles which is the same as we always use and the area around our target area is transparent, not white. The area in question is the Virgin Islands. It looks like Asobo/MS have their own water mask in the area. Could it be that there's a collision between the CGLs?
If anyone has experienced this before and resolved it I'd be much obliged to hear the solution. Currently we are looking at redoing the textures but clearly don't want to run into this issue again.
We're not sure if this is related to SU9 or not, but we only noticed it afterwards.
EDIT: Redoing the textures (including with a test generating tiles at zoom level 20 instead of 19) has unfortunately not changed anything.
EDIT2: I've noticed that the white tiles are only appearing at LOD12. I've also turned Bing World Data off and on again (and cleared the rolling cache) but although I thought it was working initially the issue has returned.
