Hello, Support Team

Multiple reports from clients indicate that moving the viewpoint causes the drawing position of Entity polyline and IonSDK gizmos to shift.
This appears to occur on devices with Intel Arc graphics chips.

OS : Windows11
Cesium Version : 1.116 and latest Sandcastle(1.135)
Browser : Chrome,Edge,Firefox

Thank you.

Hi @cccCesium,

Does it only occur on these graphics chips? Could provide a minimal sandcastle example that reproduces the issue?

Thanks,
Matt
