    My mistake - it doesn't fix the issue - the issue just doesn't occur 100% of the time.

    I had this issue because my custom shader was using the fallback "Diffuse". I changed it to "Standard" and the issue went away.

    I am seeing this in 2017.3 and the suggested workaround does not solve the issue.

    Is this going to be fixed for 2017?

    FIXED 2018.3.0a6??
    I'll guess you mean Unity 2017.3?
