When map is in 2D and altitude is low, map blinks when a label is added to map.
Thank you for sharing this with me! I was not able to reproduce this behavior, what operating system and browser are you using?
OS: Windows 10
Browsers: Chrome 75, Chrome 92
So What OS and browser are you using?
I also reproduced the problem in
Ubuntu 21.04 - 5.11.0-25
Chrome 92.0.4515.131 (Official Build) (64-bit)
Map needs to load completely to see the blinking problem so, setTimeout millisecond may need to be increased.
I initially tried using Windows 10 on Firefox and Microsoft Edge. Earlier this morning I ran the sandcastle on my Linux build using Chromium and was able to see the issue more clearly. I just posted an issue on GitHub. Please add details as you see fit. Thank you very much for bringing this to our attention!
