You need to set the user preference WebKitWebGLEnabled to @YES for your app. To have the setting apply the first time the app is run, it needs to be set early, before the WebView is initialized. In my case, the WebView instance is loaded from the main nib file, so that's very early indeed. I added this code to Supporting Files/main.m:

[[NSUserDefaults standardUserDefaults] setObject:@YES
forKey:@"WebKitWebGLEnabled"];

CEFSimple works - yes - but IIRC CEFSimple is 'you embed what you want to do in CEF' - LC has to do the opposite - we embed CEF in LC and for some reason something screws that up in 'recent' Linux releases and we are not sure what unfortunately (despite a good deal of time having been burnt on trying to figure out why in the past).

FWIW, CEF only really exists in a usable form (from what I can see) because there are some rather large companies which use it to build their clients - in particular Spotify and Steam (I think at least, they may have moved to some other means - I don't know). It used to sponsored heavily by Adobe as (I think) it used to be what they used to provide some sort of Flash standalone type thing. Spotify took over the main sponsorship of it (e.g. providing build servers and well managed releases) a year or two ago. All three of those companies embedded stuff in CEF, so the ability to embed CEF in something else whilst present perhaps doesn't get as much love as would be ideal.

For example, we had to drop using CEF on macOS quite a while back because the port of it there was using NSAutoreleasePools incorrectly *unless* CEF was the master (i.e. being extended, rather than being embedded), this would cause random crashes (earlier versions of macOS seemed to tolerate the abuse okay, but in later versions it caused a lot of instability).
