Are you also experiencing cold restarts? Here's another related thread: Cold restarts after 10.10.3 update.

Mac Mini Late 2012, Yosemite 10.10.3, i5 with 16GB RAM

You're luckier than I am then

I also hoped that the 10.10.3 Supplemental Update released on Apr 16th would help, but unfortunately it didn't

I'm experiencing the exact same issue, and even have had a couple panic restarts, which never happened before.  I came on the forums to find if others were having the same issues, and looks like they are.  These issues actually started after the supplemental update for me.

same here for me too. except my flashing bars are not colored bars but black bars and this started today and never happened before. and I too had 2 kernal panics-- one when both my mac mini's dual monitors went blank and then kernel panicked and the another when i was using safari.

I am running Mac OS X 10.10.3 Yosemite with the latest updates.

have any of you guys tried a pram reset in addition to the smc reset?

I've tried both the PRAM and SMC reset. Both before and after the supplemental update. No change

btw my bars are also sometimes black and sometimes coloured.

I am seeing the same issues.

Mac Mini late 2012

OS X 10.10.3 with sup updates

I am now seeing flashing bars, sometimes black and sometimes color striped.

I have also had a panic too.

This system has been rock stable until the last round of updates.

Just found my Mac Mini had a panic restart while it was sleeping.  Happened sometime in the last three days.

I guess I should also add that this is a late 2012 model.  2.6 i7, 16 gigs RAM.  As someone else mentioned, this unit has been rock stable for almost a year until these specific updates, and now the odd graphic bar glitching and restarts are happening.

I've had this problem as well.

I haven't noticed a pattern yet, but I've had a problem with all apps crashing after an extended Sleep. The last time the flickering bars appeared was also I was  away from the computer for a couple of hours.

The flickering bars appeared, then when I tried to launch an app from the dock, i got a panic restart.
