I’m using Kubuntu 18.04, i7-4790, AMD Radeon 460.
UE4Editor crashes when mouse moved over the Level Editor when running in Vulkan mode:

If I run UE4Editor in OpenGL mode, the crash does not occur:
$ ./Engine/Binaries/Linux/UE4Editor -opengl4
EDIT:
I’m running kernel version 4.15, and the AMDGPU driver that comes with that:
/lib/modules/4.15.0-45-generic/kernel/drivers/gpu/drm/amd/amdgpu/amdgpu.ko
EDIT 2:
I re-ran with -vulkanvalidation=5, here’s the output when the crash occurs:
