--- Comment #76 from Stefan Dösinger stefandoesinger@gmx.at 2008-06-09 05:23:38 --- Dan: I don't think Valgrind exposes bugs in the Nvidia driver. Since the driver essentially communicates with a remote machine(the GPU), it may be a similar situation like the one with the uninitialized values in send() in wineserver.
Vitaliy: Just to clarify, did you remove both the PreLoad call in LoadLocation as well as the AddDirtyRect? Do you see any other AddDirtyRect I missed?
