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)
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. 🙂
If this is caused by a third party app, there's probably no chance Apple will fix it. As you say. I wouldn't be surprised if Adobe is the baddy here. It wouldn't be the first time their apps is causing problems...
Please keep this thread up to date if you should find a solution. I'll do the same!
Flashing pixels below menu bar?
