Some examples do not work

[akovez]

When I try to run some examples (AtomicDemo, for example), I get exceptions like

Message: 0:0(0): error: Compute shaders require GLSL 4.30 or GLSL ES 3.10 

I managed to fix this issues myself with some trivial changes to the code, but I wonder, why am I getting such errors, is it a problem with my setup, or demo code needs some maintenance? I am running ubuntu 22 and use Intel uhd graphics for 10'th gen.

It would be good if you told which other demos you are referring to (other than AtomicDemo) with your "some examples" and what changes you needed to make ("I managed to fix this issues myself with some trivial changes to the code") in order to get those to run in your case, please.

I've run all examples in raytraycing folder and got results like this - https://pastebin.com/YjAfcAYS
I run an example by changing glsl shader version to 430 in code and in randomAtomic.glslcs file

The Vulkan RT examples are just broken for me

Same here I couldn't run any of the vulkan raytracing samples. Keep getting similar errors
