going from 10.12.3 to 10.12.4 introduced issues - scrambled popup windows

Thank you for the updates.

Despite much insistence, we have not heard from Apple recently about this issue, we probably need to see what happens at WWDC.
On both systems we have that can reproduce this issue we're now pretty stable with the issue reproducing reliably when GPU switching is enabled and not reproducing with it disabled.

I'd still recommend trying a SMC reset to bring the system to this deterministic state. Most likely it needs to be performed while GPU switching is enabled, but it's difficult to confirm as we can't get into the previous state.

This is all we have at the moment, I'm afraid it's not much and I can understand your frustration as I'm using an affected system myself.

Kind regards,
Carlo
