Iris 26.20.100.8141 and Vulkan GZDoom

With the release just before 26.20.100.8141 for the first time ever on my Dell XPS I was able to play GZDoom 4.4.2 using Vulkan and got almost 20% better framerate than using OpenGL.  Before that Iris driver release the floors, walls and many sprites weren't even render (or at least visible).   I was thrilled.

I saw an update appear and applied 26.20.100.8141 - and now the same graphics issues that prevented me from using Vulkan are back.

 

Is this known?  I've read lots of trashing Iris drivers regarding Vulkan but it *was* working.
