Does anybody have enough experience with Qualcomm/Adreno and SPIR-V?

I have valid SPIR-V, well according to the Lunar G validation and glsl → spirv tools.
Now, it is my understanding that this is standardization enough to not get errors when using the shader on an Android Tablet, neither should it matter that the spirv has been produced on my linux laptop. I do definitely get an error during compilation and not prior to it.

I have added the Qualcomm validation layer but it’s useless in respect to shading it seems.
All I get is an error, and I cannot find clues online, and the ones I tried which suggest optimization options (or omissions of such) do not work.

Qualcomm is useless as they offer no support for non commercial purposes.

Has anybody made any experience with that setup/hardware. Below I included a logcat snippet that gives more info on driver and error…
