The possibilities I've been investigating are:
- We're not setting the GLES context correctly
- There is an issue in the driver that is due to the way we are prompting it
- There is some sort of out of memory issue (doesn't seem to be the case as
there aren't a huge amount of textures in use)

Title:
Fails to generate texture when running zenity on Nexus 4
Status in xorg-server package in Ubuntu:
Triaged
Bug description:
Test case:
1. Run XMir on a Nexus 4:
$ Xmir :0 --desktop_file_hint=dialer-app
2. Run zenity
2. DISPLAY=:0 zenity --info
XMir hits an assertion:
Xmir: glamor_fbo.c:189: glamor_pixmap_ensure_fb: Assertion `fbo->tex != 0'
failed.
Digging into the code, the failure is occurring in _glamor_create_tex
(glamor/glamor_fbo.c). The glGenTextures is returning a 0 for the
texture and not setting an error code in glGetError.
