Just got an MSI WS60-7RJ and got the same issue on Ubuntu 16.04 with driver 384.69.
I confirm. Suspend and resume is a nice workaround.
While the suspend and resume hack is getting the job done, I was still experiencing tearing issues.
After doing some searches, I stumbled upon a tweak that takes care of it and has the side effect of taking care of the sluggish performances too :
No more need to suspend/resume!
Hope it may help find a definitive solution.
Same here on a Dell Precision 7520. The tweak fixes it for me. Thank you for posting it!
Good to know you have WAR for this issue. We are still investigating this issue. We’ll keep you posted.
Hi guys. Just wanted to say many thanks for this workaround tip!!
I’ve had a new Thinkpad P51 sitting useless on the desk for over a month because of Ubuntu graphics issues. Currently running the Ubuntu 17.10 final beta with kernel 4.13.0-12 and was getting really bad responsiveness e.g. in window resize both laptop 4K internal display and displayport-connected Dell 34" Ultrawide screen. Now with BIOS in Hybrid mode (cannot even test discrete mode because with that set, boot freezes in plymouth disk encryption prompt), nvidia-prime package installed and nvidia driver enabled in Ubuntu Software & Drivers app it works and feels normal, not to mention the increase in glmark2 and glxgears results. I mean, WITH the suspend/resume workaround. Without doing that it’s just plain misery. I’m not a graphics intensive developer by any means, while debugging this found the nvidia-settings utility nicely shows the PowerMizer info and the graphics clock, clearly it was stuck in the lower MHz counts before doing the suspend.
Yay, finally I can use this laptop! Of course Nvidia, please come up with the real fix. Thanks.
And just to add regarding reproducing the issue, you WILL notice it when you have the issue. With nothing else running, just resizing a terminal window on the 4K internal display makes the window border lag behind the mouse cursor couple of seconds and hundreds of pixels, even with moderate drag speed. Basic up/down scrolling in Firefox makes you wait, etc.

We have fix this issue and fix will be available in upcoming driver release.
This is great news.
It took you a while, however I really appreciate your work and I look forward to the next driver release.
And again thx to the community, who made me aware of the workaround, that really increased the user experience I have with this notebook.
Please test 384.98, 387.22 drivers and share feedback.

Now the problem is gone, thanks for the fix.
