Hi Christian, Alexander,
Kmemleak reported leaked data structures and the GPU hung a bit after.
Could this be caused from DC?
Info in attachments.
I'm not sure if my previous email got overlooked, or if simply, there
are no suggestions at this moment. Sorry for kind of re-sending the
email.
Regards,
Luís
