Having the same issue, but it seems to be localized to Vulkan. I've confirmed
this on a Ryzen 2300U laptop and a desktop Ryzen 2400G. I have a save file in
Pac-Man Champion Edition DX+ that guaranteed will crash the system within 5
seconds of loading a time trial screen on both laptops. Same save file works
fine on a proprietary nvidia card, and on (cherry trail) intel drivers, so this
looks like it's a Vulkan bug exhibiting itself through DXVK on Raven Ridge. 

Tested on 19.1.0_rc2 and git current as of this date: both exhibit identical
issues in Ubuntu and Gentoo.
