It may be related to the brand new mesa/src/gallium/auxiliary/util/u_live_shader_cache.c I don't know the inner details of this (I stay away from anything GL), but it seems there are some GL shader usages which which will trigger a full compilation of an already compiled shader. @alex, maybe that's what you were talking about? As I said, I may be totally wrong though. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
