How to debug #11

I am currently trying to get swiftshader vulkan implementation working on a imx7 (without GPU). In the end I am are trying to run flutter : https://github.com/meta-flutter/meta-flutter/issues/26

However when i add swiftshader and sasha samples on a build with wayland support the examples dont run correctly. The samples do find the swiftshader vulkan implementation, but when they are started only a black (or with some samples blue) background appears. The color does seem to come from the sample implementation.

As i suspected the problem might be in the wayland connection, i tried to compile the software with directfb support, but unfortunately i could not compile this. (See issue)

At this point a actually do not know what to do any further. How can i test the swiftshader and samples so I can find out where it goes wrong?

This layer is tricky to get setup correctly. The dunfell-no-mesa uses mesa as-is. For RaspberryPi4 using latest Mesa Vulkan support (required), the dunfell branch works. For Other targets that don't require more recent Mesa, or Mesa at all dunfell-no-mesa should work. What branch are you using?
