--- Comment #3 from Pavel Ondračka drakkk@centrum.cz 2010-06-24 01:38:30 PDT --- With current mesa git compiler error looks different:
r300 VP: Compiler error: Ran out of temporary registers Using a dummy shader instead. If there's an 'unknown opcode' message, please file a bug report and attach this log.
However rendering problems still remain.
