Point Entity flickering in Chrome

[Christine_Lee]

Hi,
I used this example http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Points.html&label=Showcases to create points on my cesium map and I notice the points are rendered oddly and flicker. I am using the latest version of Google Chrome (58.0.3029.110). I can display the same example in FF and the point renders as expected. Does anyone know of a solution?

Thanks,
Christine

Hi Christine,

Weird – not an issue I’ve seen before. Could you try clearing your cache in both browsers (or running in incognito mode) and running again? Sometimes caching causes odd problems.

Also, what operating system and graphics card do you have?

Best,

Hi Rachel,
Thanks for responding. I am using a Windows 10 VM. Graphics card on the VM: VMware Virtual SVGA 3D Graphics Adapter.

I tried running on incognito mode and got the same results.

Hi Christine,

This could potentially be an issue with the VM. Can you paste the results of visiting http://webglreport.com/ ?

This will give us information about your system’s WebGL support.

Thanks,

Christine, does that Sandcastle example itself flicker for you? Or does the flickering only happen in your application? While this sounds like it could be a Chrome bug with your VM, it’s hard to tell without being able to reproduce it on our end.

I confirmed that it does flicker in the Sandcastle example, so it does give me hope that it’s limited to my VM. Every other Sandcastle point example I’ve tried in chrome outside of the VM seems to display correctly.
