Switcher (Alt + Tab) switches to wrong window in Windows 10 20H2 #62

Closed riverar closed 3 years ago

riverar commented 3 years ago

On Windows 10 19042.630 (20H2), the switcher at times switches to the wrong window. (This is reportedly fixed in 20231 and higher, so test with a non-Insider build.)

Purpose of filing the bug here is to increase servicing pressure. We don't want to wait until Windows vNext for this to be fixed. This is a productivity slayer.

Steps to reproduce

  1. Open Settings and navigate to System > Multitasking, and ensure pressing Alt + Tab only shows [Open windows only].
  2. Open Notepad
  3. Open Microsoft Edge
  4. Alt + Tab between Notepad and Microsoft Edge twenty times
  5. Observe the wrong window is focused at least one of those times

Expected

Oscillation between the last two windows that had focus, Notepad and Edge in this case.

Actual

Oscillation between the last two windows that had focus, with occasional focus of other windows.
