Bug Description

Web pages appear garbled and graphically corrupt when displayed on the webbrowser-app under unity8 on a Kabylake Dell Inspiron 5378 using the default unity8 session currently included with Ubuntu 16.10:

This behavior occurs 100% of the time on this hardware under unity8 and does not occur when webbrowser-app is started under unity7.

Attaching output of apport-bug for unity8 and webbrowser-app as well as application-legacy-webbrowser-app-.log from ~/.cache/upstart. Let me know if there's any other useful information I can gather.

I'm adding Oxide to the bug, as the browser chrome is being rendered ok. I also see these strings in the browser log:

[0111/095625:ERROR:layer_tree_host_impl.cc(2189)] Forcing zero-copy tile initialization as worker context is missing
[0111/095625:ERROR:oxide_compositor_gpu_shims.cc(258)] Error creating EGLImage: EGL_BAD_PARAMETER
Cannot find EGLConfig, returning null config

Which make sense as those kinds of visual artefacts are typically GPU tiling problems.

Yeah it's a general problem with oxide and friends. Not just because the corruption is confined to the browser area, but also because I've seen exactly the same corruption pattern on some systems with Android-x86.
