Black bar appears below the Windows taskbar while Keyviz is running

When Keyviz is running, a black bar appears at the bottom of the screen below the Windows taskbar. The issue is especially visible when another application, such as Chrome, is maximized.

The black area disappears after Keyviz is completely closed, so the issue appears to be caused by a Keyviz overlay window.

Steps to reproduce

1. Start Keyviz.
2. Open an application such as Google Chrome.
3. Maximize the application window.
4. Look at the area below the Windows taskbar.

Actual behavior

A large black bar appears below or behind the taskbar. This makes maximized applications look as if they do not fill the entire available screen.

Expected behavior

Keyviz should display keyboard and mouse inputs without changing the appearance or usable area of the Windows taskbar.

Workaround

Completely exiting Keyviz removes the black bar. Closing only the settings window is not sufficient.

The problem started immediately after installing and launching Keyviz. No taskbar customization tools such as TranslucentTB or Windhawk are installed.
