Monitor flickers when using trackpad
8 month-old MacBook Air, running Yosemite v10.10.3
Apple Thunderbold monitor, 27", also only 8 months old
Apple Magic Trackpad
My monitor suddenly started flickering whenever I move my finger and the cursor across the page in a browser. Happens with both Safari and Firefox. I've updated both browsers to the latest versions, but it didn't help. Happens in all browser sites, not any particular one. Doesn't seem to happen on any apps.
Is this a monitor issue, a trackpad issue, or does it have to do with the laptop itself? Back in 2010 and 2011 there were lots of complaints that this was happening with the MacBook Pros, so I'm wondering if it could be a computer problem.
And what should I do to fix it?
