Hi,

The following GStreamer pipeline causes screen to become green with
v4.9-rc4+:

gst-launch-1.0 udpsrc uri=udp://239.1.2.2:5100 reuse=true caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264" ! rtph264depay ! h264parse ! v4l2video1dec capture-io-mode=dmabuf ! kmssink name=imx-drm sync=0

Reverting "drm/imx: ipuv3-plane: Skip setting u/vbo only when we don't
need modeset", commit 81d553545a1510ff7c7c00cbc9b57d6172d411a4, fixes
the problem.

Hardware is Gateworks Ventana GW5400, i.MX6Q, HDMI output, no X (console
only).
