Bug Description
Tested on two notebooks.
Bug appears only in the 13.04 version. 12.10 is OK.
Dubblechecked by booting a 12.10 version on USB stick (on the 13.04 notebooks).
Problem:
OpenGl shading language (GLSL) uniform variables seem to stay undefined, or lose their value somewhere.
Tested with a WebGl app as well as a C++ (Qt) application.
This bug is also reported a driver issue.
If it is related to this driver issue, why is the (old) buggy driver re-installed with 13.04?
thanks.

I have filed the bug at https:/ /bugs.freedeskt op.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.
