Hi johan,

I need few inputs.

1. Is this issue is seen when u connect a external display directly to laptop
without dock ?

2. Have u screen the display tear issue on embedder panel of laptop.

3. As i see from dmesg logs your external display resolution is 1920x1080, have
u observed the issue with other monitors or with other resolution modes.


4. could you please let me know if you see this issue after running below
command

echo "2 0 0 0 0 0 0 0" > /sys/kernel/debug/dri/0/i915_pri_wm_latency

Thanks ,
Anshuman
