After cesium1.103 version, Cesium flashes when updating entity positions, such as when updating polylines through polyline-positions. But this issue did not exist before version 1.103.
Hi @WwhCesium,
Is this issue still occurring in the latest Cesium version - 1.132? We’ve made some changes recently to address flashing while updating material properties, and I wonder if these changes may have addressed your similar issue.
If it’s still occurring, it would be great if you could provide a sandcastle that demos the bug, and if you’d consider opening an issue in the Cesium repo!
Thanks!
Matt
It still exists in version 1.132. Flashing will occur through the method of entities. polyline. positions=Cesium. Cortesian3. from DegreesArray (data).But the flicker problem can be solved through the method of entities. polyline. positions=new Cesium.CallbackProperty(function () {return Cesium. Cortesian3. from DegreesArray (data); }, false);。Why does flashing occur when updating positions directly, but not when updating through callback functions？Before version 1.103, updating positions directly would not cause flickering issues。As long as it is created through entities, updating the position will cause flickering issues
