video showing flickering
We have written a pepper-plugin for chrome using the (internal) API to render with EGL our video content.
On a Intel-GPU we see flickering and corrupted textures.
This effect is seen with the "current" Intel driver on Debian Stretch but not on Ubuntu 15.10.
Starting with this information I could identify via 'git bisect' the first "bad" commit which introduces the issue:

Since the environment is a little bit complex to provide a reproducer easily, I've added some videos showing the issue
