After I updated to Mavericks I noticed that a strip of pixels will randomly flash at times right under the menu bar. The line is maybe 1/4 of the screen in the center. If I go into mission control or launch pad it goes away for a while but comes back eventually. Does anyone know what would cause this? I have tried rebooting/updating to 9.1 and it still happens.
MacBook Pro, OS X Mavericks (10.9)
Brutal! How many people have gone in to an Apple store to go over this issue & are you sure it's not a hardware, gpu issue?
If it's software...which from the discussion I think you've all determined it is, it would seem it would be easy to find what's causing it...it occurs 110% of the time when you use the hot corner -> desktop option. It goes away 110% of the time when you then use any other hot corner. Brutally annoying, I'm going to go to an apple store to see if they've got an answer, it doesn't make sense this isn't fixed...
If it was a GPU issue then it would be narrowed down to only one line of macbooks since all of them use a different GPU.
It has to be software but determining what software would take forever and since, like I said, my girlfriends brand new macbook air is doing this right out of the box it's not something that we have downloaded. I even turned off every icon that you can turn off in the menu bar and it didn't help. It's in the software but no one knows where.
Good luck though
Has anyone had any luck with this?
I'm also getting this problem - bought my MacBook 15inch Retina in November, it had logic board replaced at 2 days old then when it came back it started doing this. I've been in and out of the Apple Store about 6 times since then (first they replaced the screen before discovering that it's software).
Eventually they gave me a brand new MacBook two weeks ago, I slowly installed stuff and copied files from scratch - didn't just restore from Time Machine - and today I've noticed it happening! Was never able to replicate it manually before - it would just start flickering quickly whilst in Safari - but now I can replicate it each time I swipe to the bottom corner to show the desktop!
Going to call Apple Support this week hopefully, I don't want to go down there again and leave it for a week.
It's a system ghost (obviously software related) that we could be chasing for years, I've had enough with trying to figure it out, time to get on with my work as it doesn't really affect my use of the laptop much.
Hopefully some smart fella will pinpoint it in the future and tell us about it on here, if not I hope some kind of software update just makes it go away one day.
At least when I come to selling my MBP and getting a new one, the new owner of this machine will most likely be completely free of the issue unless he/she happen to put the offending piece of software on it, which seems like a slim chance as there's not that many of us having this issue in the grand scheme of things.
Problem after updating to 10.9.3 seems gone =)
Let's hope it's a done deal!
Well that's suprising because every beta still had the issue

Still remains as annoying as ever post-update for me 😟
Problem still remains for me on 10.9.3
Sorry, I was wrong...problem is still there!ðŸ˜
OS X Yosemite should be out soon!
Hopefully this upgrade will kill off this 'Desktop' HotCorners flickering pixels issue once and for all, fingers crossed, let us know if you have any success (or failure for that matter).
Been on Yosemite GM a couple of days now and not seen the problem yet. I haven't however used VLC yet and it usually then whilst using a hot corner.
Sounding positive mate 🙂
Mine does it every single time, with pretty much any application window that leaves off the top of the display when using the 'Desktop' HotCorner, so post-Yosemite upgrade I'll know immediately if it's solved the problem or not.
I can confirm that the new OS X Yosemite has officially killed this bug 🙂
I'm gonna go ahead and bump this thread, as I'm still experiencing this on OSX El Capitan 10.11.1 on my 13-inch rMBP (late 2015).
I should mention that my friend is on the same OSX version but on an older 13-inch MBP Air (mid 2011) and he's not experiencing this issue. Incidentally I used the exact same model of MBP Air during my whole Yosemite period and I didn't have this issue at all.
Can someone else confirm that this has resurfaced in El Capitan?
Confirming issue on 10.9.5. The flickering line will go away when the top menu is redrawn - clicking the desktop helps. This happens most notably on Chrome for me, but it's not limited to it. I use VNC, VLC and PSCS6, so yeah... 😉
One difference - this being on a Mac Pro Mid-2010.
Not holding my breath for Apple to fix this, actually. 🙂
Flashing pixels below menu bar?
