On my new Omen 15, my dual display setup is unstable

[jmbezeau]

I have a Thunderbolt Dock WD19TB which is connected to all my USB devices as well as my two 27 inches monitors. Everything works flawlessly with my home office setup (a Dell XPS laptop).

I purchased the Omen by HP a week ago. I connected the USB-C connector to the Omen and magically everything was working perfectly. However, this didn't last. My monitors are showing flashing artifacts which cover from the whole screen to half the screen. This happens every 20 seconds or so. Sometimes, a monitor will turn black; in a middle of a raid for example, then turn on again. Windows doesn't see this, there is no event in the eventlog nor in the nvidia app.

Sometimes, after a restart, everything is great, no glitches and the display is perfect, it can last for a whole day. The first time it happened, I thought I had fixed it. I had turned the USB-C connector upside down; so it was the laptop connector.

Remember, everything works fine when the dock is connected to my office laptop.

Any ideas?

I have tried to change the refresh rate of both monitors to 59 hz instead of 60. It worked for a couple of hours.

I have tried to update all drivers I could get. But Windows 10 is managing most of them.

I have followed the instructions from HP troubleshooter for screen problems, I reset both my monitors to factory settings, and behold: glitches are gone. It's been half a day. I will write again in a couple of days to tell  if it last.

After a day, the glitches were back.

I have installed all updates from HP Support assistant and Windows Update. I have also installed the latest nvidia drivers.

I have an open case 5046185256 for this issue.

I have tried switching cables and it didn't work either.  I can't connect my dual display directly to the displayport connector, because I don't have a minidp to dp converter. Anyway, this has to work with my thunderbolt dock.
