Description Ian Romanick 2009-09-16 08:15:22 UTC

The GL_ARB_vertex_program spec says that relative offsets are limited to the range [-64, 63].  However, it seems that all implementations except Mesa support a much larger range.  Some applications, such as Wine, rely on this behavior.  Mesa should match what the other guys do here.

See the discussion in bug #23946.

Was this fixed already? 

At least the the test case for Wine in bug #23946 seems to be working quite well now (except for the "glare" filter)

Comment 2 Marek Olšák 2010-08-03 15:28:58 UTC

I've increased the offset range to -4096/4095 in the parser by commit 0614006d090902324149387ec150231b647928fd. Closing..
