This doesn't sound like correct or expected behavior to me. Can you please file a bug at http://bugs.webkit.org/ with steps to reproduce?

If you launch any WebGL web application, say our Planetarium demo ( <https://www.blend4web.com/apps/webplayer/webplayer.html?load=../../assets/interactivity/solar_system/solar_system_en.json>https://www.blend4web.com/apps/webplayer/webplayer.html?load=../../assets/interactivity/solar_system/solar_system_en.json <https://www.blend4web.com/apps/webplayer/webplayer.html?load=../../assets/interactivity/solar_system/solar_system_en.json>) which uses frame buffers, and make Safari application go to background (press home button, press power button, wait 10 seconds and turn it on again), it appears that Safari will brake the frame buffers with gl. INVALID_FRAMEBUFFER_OPERATION error.

Unfortunately I could start it only in the simulator mode (with the help of this article  <https://webkit.org/blog/3457/building-webkit-for-ios-simulator/>https://webkit.org/blog/3457/building-webkit-for-ios-simulator/ <https://webkit.org/blog/3457/building-webkit-for-ios-simulator/>). It works fine and doesn't crash. I was trying to find some info on how to run it on a mobile device, but I didn't succeed. Could you please tell me, how I can run mobile Safari with the latest WebKit version on a real device?
