GUI issue: when Dark theme is used, selected items in Options menu lose highlight color (completely) on lost focus

Codec version: 18.5.0 (Mega)
OS: Windows 10, version 1607, N edition

What happens when we select an option (User Interface):


What happens when we transition focus to a property (Control buttons size) of the selected option (User Interface):


The highlight color doesn't dim (unlike when Windows Default or Light theme is used), it disappears altogether.

By the way,

What is the purpose of the Windows Default theme? Is it to auto-detect the brightness level of the currently used Windows theme, or is it to imitate the color scheme of the classical Windows (95, 98, 2000) look?

If it's the latter, then I wonder what's the purpose of the Light theme, since it's the same as the Windows Default theme.


Thank you

Then it follows the Windows theme, which can be either light or dark.

Admin, in this case I would also like to report that when I have the High Contrast Black theme selected (in Windows' Control Panel), the Windows Default theme (in MPC) doesn't switch to the Dark colors and the player remains light.

High contrast is not supported by the player.
