(Keywords: correctness)

We have some reports of suspend-resume issues. We suspect that we don't properly check for context loss exposed via the khr_robustness extension. and that it might be the cause of the issue.

As this is on NVIDIA, this could well be video purging. There is NV_robustness_video_memory_purge, which notifies applications when the video has been purged (https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt)

I believe I fixed this as part of bug 1682876. We need to turn on robustness with EGL in bug 1680759.
