Hi!

Since updating to 1.121 (I skipped directly to 1.122 but could not reproduce this with 1.120 or prior) I have a label tileset that keeps flickering.  
Is there something wrong with my data? (I haven’t changed this data since ages though)

[Here’s a sandcastle with the tileset in action](https://sandcastle.cesium.com/#c=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), try zooming or moving around Switzerland and you should see black flickering all over the place.

Hi @pakb ,  
Thanks for your note and welcome to the Cesium community.

This does look like a bug that should be investigated. Thank you for providing a clear sandcastle that demonstrates the issue. Since you mentioned that you data has not changed, it seems likely this a problem with the library and not with your data. I went ahead and made a bug report with the info you shared here in the Cesium repo [Flickering label tileset since 1.121 · Issue #12287 · CesiumGS/cesium · GitHub](https://github.com/CesiumGS/cesium/issues/12287). Feel free to follow the issue or add more useful information.

Thanks again and we hope somebody form the community or Cesium team can find the root cause and make a fix soon.  
Best,  
Luke

Thanks! Then I’ll add myself to the subscribers of the GitHub issue 😉
