Comment 1 Thomas Lübking 2010-09-04 23:33:27 UTC

please attach the output of "glxinfo", but the gpu/driver is likely detected to be (and really) not capable of the blur effect

(also: which driver do you use? fglrx or radeon?)

Comment 3 Wojciech Ryrych 2010-09-04 23:55:54 UTC

I use radeon driver.

Comment 4 Martin Flöser 2010-09-05 08:08:53 UTC

Sorry, your driver is not capabale. It only support OpenGL 1.5 and some required extensions like GLSL and shader objects are not available

Comment 5 Fredrik Höglund 2010-09-05 17:12:37 UTC

This is actually a duplicate of bug 243191.

The blur effect doesn't require GLSL, the missing extension is GL_ARB_texture_non_power_of_two.
