I'm having the same issue described here on Ubuntu 16.04, running on a MacBook pro. The alt+tab applications switcher seems to randomly popup out of nowhere, perhaps from some interaction with the trackpad. Does anyone have any ideas how to solve this issue?

    I have the same problem and for me it doesn't seem to have anything to do with activity on the touchpad as it happened when I definitely wasn't touching it. It only happens on laptops, though. I never saw it on a desktop PC, nor on a Raspi, nor on a virtual machine, no matter whether running on a laptop or on a desktop PC. It definitely happens with different laptops but somehow it doesn't seem to have ever happened to anyone I know who uses Ubuntu (I know quite a lot of people who do).

  • Any inclination as to what might be causing it? Super annoying bug

    No, absolutely no indication (I suppose you meant "indication"). Not even the moon phase. But it's not about your laptop being a macbook because mine are not. I think you can't even reduce it to the touchpad as there are many other differences between desktop PCs and laptops: WIFI is built in, Bluetooth, has a battery, has a webcam, has a built-in microphone, etc.

    All I figured out until now is that it happens very irregularly and that it definitely isn't the keyboard actually pressing Alt+Tab. I figured this out by switching to a different TTY while it happened and switching back shortly after so that it was still switching applications. There were now ^[ printed on the TTY which would've happened if it was entered by the keyboard.
