When I run UE4Editor on linux I get a lot of errors that show: LogVulkanRHI: Warning: Failed to allocate Device Memory, Requested=262144.00Kb MemTypeIndex=7 and then crashes with a large output. If I run vkcube first and then run UE4Editor the errors go away and UE starts completely. There seems to be something that UE is not initializing correctly that vkcube does.
I’m running openSUSE tumbleweed (20190512) with nvidia driver version 418.56 on xorg.
Full error output:
