I have filed the bug at https://bugs.freedesktop.org/show_bug.cgi?id=70322,
because I think it related to mesa.
Still, also affects the ubuntu upgrade to 13.4.
I downgraded back to 12.10 in order to keep openGl working.

opengl ES isn't working correctly any more.
I had a WebGL app running nicely in FireFox and Chromium (Ubuntu 12.10).
I upgraded from 12.10(64bits) to 13.4 (64bits).
Now it
Just tested an existing desktop Qt opengl ES application, with same kind of
