This happens on multiple tests and bots, WebGL context is just null. E.g.: <http://build.webkit.org/results/Apple%20MountainLion%20Release%20WK1%20(Tests)/r157307%20(13730)/compositing/webgl/webgl-background-color-diff.txt>. Dean, what can be done to narrow this down?
(In reply to comment #0) > Dean, what can be done to narrow this down? I'm not sure. I think I'll have to add some logging to explain why context creation failed... is there a way to enable a logging channel in a test?
Regular console logs (stderr) will be preserved, and they can be limited to engineering builds with an ifdef I guess.

Created attachment 219371 [details] Add logging Looks like there is no way to silence the logging in production builds and have it in release ones, so we'll need to remember to remove this.
Comment on attachment 219371 [details] Add logging Since this was described as temporary logging and this was 6 months ago, marking review-.
Not sure what our plan is for this. Dean? The particular test mentioned in this bug is still flakily timing out, see <http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=compositing%2Fwebgl%2Fwebgl-background-color>.
