    Is this actually fixed in any available version of Unity? It was initially reported as fixed in 2017.1 but was not, and now it says fixed in 2017.2. I just tried the available beta of 2017.2 and the problem persists.

    From Unity: "I have good news, this bug has been fixed and is going to be backported to 2017.1 and 5.6. I'll get back to you as soon as I know which patches will contain the fix." < great :) So hopefully it'll be coming in a patch release soon...

    Instead of I develop more games and make money most time I only track and wait for new Unity releases and fixes, just to realize that when you fix one thing 3 more become broken. Please stop making fixes, thank you.

    It's not just GLSL, vulkan and metal compilation when having dynamically indexed uniforms experience the same issue.

    I think this bug needs higher priority..It is a regression after all :)
