[Linux] [Vulkan] Mip-Maps not Saving/Generating


I have a strange issue in my Project. Every time the Editor is started, some of the Textures are missing Mip-Levels.
After saving the asset again, everything is ok, until the Editor is restarted.

Here is a Video of the Problem:

In this Video 2 Normal-Maps of the Water are affected. But it can be any other texture.
Sometimes even parts of the UI are missing.

When I run the Editor with -opengl4 the issue is gone (But opengl has its own problems).
I was not able to reproduce it in a smaller Project.

Removing the Intermediate-Folder seemed to help sometimes, but thats also not reliable.

What could I try, to find the source of the Problem?

My Hardware:

  • OS: Debian 9 KDE
  • CPU: Intel Core i7-6900k
  • RAM: 32GB
  • GPU: Nvidia Titan X
  • Driver: 418.56 (Also happened to
    the 396-Driver)
