Yes, if I switch to windowed-mode with alt-enter, I can then switch between windows with alt-tab even when running '-video opengl/bgfx/gdi'.

As far as my personal experience goes, 'alt-tab' on Windows works always, even when running applications full-screen.

Perhaps. But that doesn't explain why alt-tab when using '-video d3d' and running full-screen works as expected (does switch between windows).
