GStreamer freezes after the Nouveau unexpected pageflip

[Sergei Vorobyov]

Greetings,

my Gstreamer application is quite reliable, but it hangs/freezes once in a
while (very seldom) with the following syslog message:

Sep 11 00:21:15 wsl kernel: [226699.539463] nouveau E[     DRM] unexpected
pageflip
Sep 11 00:21:28 wsl kernel: [226712.737584] nouveau E[Xorg[1691]]
nv50cal_space: -16
Sep 11 00:21:28 wsl kernel: [226712.920277] nouveau E[Xorg[1691]]
nv50cal_space: -16
... (the same repeated many times)

Is it a known issue for GStreamer or should I address the Nouveau
development team with a detailed bug report?
