I experience no crash, but the steam overlay doesn't display in Vulkan mode, I see a faint flicker and then it disappears. In OpenGL mode it displays correctly.

After today update of libdrm from PADOKA PPA to 2.4.94+git1808281609.f3d90e8~b~padoka0 the problem does not happen anymore.
Nothing extracted yet.
To reproduce:
Set graphics API to Vulkan
Set Steam Overlay as enabled
Set graphics preset to Ultra
Doom freezes after intro videos, loading meter stops at 99%, and I can hear menu music.
