Do you know whether kdenlive does GL and VDPAU calls from parallel threads?

Separately, what version of libdrm(_nouveau) do you have?

Maybe I made a mistake, I was advised to report the problem here, but I was on
another forum and one user tell me that the problema maybe wasn't especific
on
the driver, but could really be on Kdenlive. I really know few about this
things and I think I could not help this, I'll try to contact Kdenlive's
support to show the mistake, thanks for the help.

I upgraded Ubuntu to 16.04 and Kdenlive to lastest version, but the problem
continue, I'm a normal user and I don't know how does GL and VDPAU calls
from
parallel threads, and the version of libdrm(_nouveau)is
2.4.67-1ubuntu0.16.04.1.
