App Switcher / Top Left Hot Corner Broken?

[IncensedCape]

Hi, I've had a problem with the app switcher since upgrading to 8.1 and was wondering if anyone has had the same problem.

When I hover the cursor in the top left corner when two or more apps are happen, I get small white outlines instead of the small preview images that I used to get on Windows 8 (screenshot attached to this thread, with settings), making it impossible to see what application I'm switching to!

PC:
Dell Latitude E6220
Windows 8.1 Pro
i7-2640M @ 2.8GHz
4GB RAM

Would appreciate any help, thanks =)

Did you try moving the pointer into the upper left corner until you see those boxes, then moving the pointer slightly down?

Hi Xunile, yes I've tried this, just get the same white outlines when I move my pointer downwards.
