Hi.I've got an iPad Air 2 and recent iOS 9.2.There is an issue with it. I'm currently working on WebGL web application. If you launch WebGL web application, using frame buffers (for example this demo from Chrome Experiments: http://labs.fluuu.id/tubes/), make Safari application go to background (click the home button, then double-click the home button, press the Safari icon in the multitasking bar), it appears that Safari will clear the frame buffers.My question: Is there a way to restore framebuffers?Thanks
