Hi , that is happening on my system lately. It wasn’t on 415.25 but now happens on 415.27 via Nvidia Prime.
It completely hags system. That is the output of
journalctl -b -1
:

Please check if it’s related to prime sync by turning it off using
xrandr --output eDP-1-1 --set “PRIME Synchronization” “0”
and then running the Witcher
You can play Witcher 3 for hours with zero problems when PrimeSync is on however when you quit from the game and turn back to desktop , hovering your mouse for 1 second hangs whole system. That is when timed out issue happens.
Are you playing the Witcher at 1080p or a lower resolution, i.e. is a mode switch involved when exiting to desktop? If so, can you provoke the freeze when simply switching the desktop to a lower resolution and back while prime sync is on?
Yes, there are still some more issues regarding the Vulkan+PRIME sync combo, depending on if/which vsync method the application uses. Does the Witcher have different settings for that to further narrow it down?
I found the following closest notebook having similar configuration as ZenBook Pro 15 UX550GEX with GP107M [GeForce GTX 1050 Ti Mobile] and driver 415.27.
Installed Ubuntu 18.10 and downloaded Withcer 3 but unable to launch it.
As a workaround, I installed game White Night and quit after some time but didn’t observe any hang on notebook.
Please confirm if you used steam to launch Witcher 3, if yes, please let me know exact steps followed to launch game.
Moreover, if you face same issue on any other game, please let us know.
Go to Steam settings , enable SteamPlay for all titles and select Proton 3.16-6 beta. Obviously you will need libvulkan installed.
No , i only came across in Withcer 3 somehow.
Play the game at fullscreen , vsync on then quit the game and hover your mouse on the screen immediately. If you wait 5-6 seconds after quiting , that timed out issue cannot be triggered.
Also it would be better to test it on Ubuntu 18.04 base since 18.04 is the LTS one and Mint 19.1 is base on Ubuntu 18.04.
They do backport stuff from short term releases like Ubuntu 18.10 to 18.04 eventually but solely testing on 18.10 won’t cut the usual end-user experience. Since other popular distros based on Ubuntu ( such as Elementary OS etc ) are also based on LTS release.
