This is now resolved by disabling rgb10 configs by following commit. However a real fix is still needed to be able to enable the configs.

    dri_util: remove ALLOW_RGB10_CONFIGS option (v2)
    
    This is unused because it's for libGL/libEGL, not drivers.
    
    v2: i965 was wrong, because it used dri_util instead of its own config.

Verified, gnome-terminal content, alpha-blended window borders with Ubuntu compiz and Chromium tooltips look fine again with latest Mesa git.

Should this be kept option until there's a real fix?

Yep, let's leave this open until fixed. Would be good to get exact sofware component versions from the CI machines that hit this, if possible.

I've tested that this is fixed for Ubuntu 18.04. I enabled 10bpc visuals and can see bunch of them in glxinfo list. Desktop and icons render correctly. Will do further testing with 16.04 later.
