I think that's some issue on my side, but may be someone had similar one.

Ok. Let's fix it find / | grep libOpen

WAT?

ocl-icd - same result

Resolved, but that was not obvious.

1. (I'm not sure that it's needed at all) Disable composite option at driver. (I disabled it when I installed calculate xfce desktop in GUI installer)
2. dmesg shows that initialization is not ok (uvesafb: cannot reserve video memory at 0xc0000000) Solution: disable UEFI (my bios has only two options:UEFI and UEFI+legacy, so you need some explicit options when configuring kernel boot. I played some partitioning params at GUI, ex. EFI partition disabling). So you will have one less error in dmesg.
3. Ensure that x11-drivers/ati-drivers installed. Don't try wget for fast loading .zip from amd site.
