First time this problem occured today, simultaneously on different computers, and of course during a presentation
I had made a pretty large webscene and was loading it into the viewer (from arcgis.com, in Chrome). Everything was loading and parsing fine and the terrain and models was starting to come into view. Then suddenly everything whites out in the browser window except the UI stuff.
When I reloaded the webviewer Chrome gave a WebGL error.
Of course everything worked smoothly last night.
Has anyone experienced something similar, or have any theories as to what might cause this webGL crash? Of course after rebooting and updating my videodrivers, everything seems to work fine again, but I would like to know what I can do to prevent it in the future.
