Description Sven Gothel 2013-05-17 04:20:46 CEST

GLSL spec [1.30 - 1.40] section 4.5.3 states that fragment program requires a [default] precision
for float values.

Failure to do so, causes a bug as reported here:

Note: GLSL spec >= 1.50 does _not_ require such default precision.

Comment 2 Sven Gothel 2013-05-17 04:53:45 CEST

Needs verification on said machines w/ GLSL [1.30 - 1.40] which failed!
