Problem with 3DTile in Cesium 1.107 and Cesium 1.107.1

Hello,Cesium team, after I updated CesiumJS version from Cesium 1.106 to Cesium 1.107,one of my 3dtile models become flickering,I also tried Cesium 1.107.1,but nothing changed.
Here is the code for loading model,it works well in Cesium 1.106.

And another problem,the same 3dtile model show different color at different time,never set Cesium3DTileStyle.
