did you resolve this?
i have ran C3 on a few different chromebooks and never had an issue.
only thing i can think is Chrome stopping the window because its a popup some how?
maybe try the setting where the preview opens in a new tab, rather than new window?
So strange tried EVERYTHING, but it seems to work using firefox only, i really want it to work w chrome.
Its like the webGL is crashing upon preview, even the editor crashes.
