If you can reproduce this on your computer, you should be able to with the LunarG Vulkan SDK cube program. Run it like so:
$ ./cube --present_mode 1
You need to run a compositing window manager and alt-tab out or go to a different window to reproduce this, as far as I can tell. It doesn't happen when running under XMonad or Kwin with composition disabled with Alt+Shift+F12. You should see the screen blank out to black.
OS: Arch Linux x86_64 GPU: Radeon RX 460 2GB Display connected by DVI-D Window managers with the issue: Kwin, Mutter
I haven't tested whether the issue shows up with Wayland yet. I don't expect it to, but if it does, I'll leave a comment.
