There is a problem on some Surface machines (Surface Pro 4 specifically) where the thumbnail previews on the taskbar disappear quickly… to quickly to be useful. The issue only occurs when using a power adapter and not when running on battery power. The solutions are:

  1. Disable the battery driver in the Device Manager (Microsoft Surface ACPI-Comliant Method Battery)
  2. Replace the power adapter (model 1625 seems to be problematic, and model 1706 seems to work fine)
  3. Update registry settings (see link below)
