(Solved) Why warcraft 3 reset brightness setting after restart?

[WC3Wonderer]

Warcraft 3 Frozen Throne 1.26a. Windows 10. I set brightness to ~1.2. Game become brighter. I restart the game and it dark. Brighness slider shows 1.2 but it looks like 1.0. Changeing the values to 1.5 or to 1.0 does not make the game brighter or darker. In order to make the game bright I need to change resolution. After changing resolution brightness slider works until I quit the game. Onother way is to restart the game five times. Four of five is dark. One of five is bright. It's like critical strike. Very funny. Who knows whats the problem and how to fix it?

Spoiler: Brightness option

That's very weird. I haven't encountered such a bug like this before.
Here's my proof (see spoiler below). I set my brightness to the exact same level as yours (around 1.5), then restarted the game. And the brightness option doesn't revert back to 1.0.
Have you changed your screen resolution to the maximum setting based on the recommended ones by your display (I'm using 1080p)???

Spoiler: WC3 Brightness

P.S: I'm using the 1.29 version of Warcraft 3. It could be the main cause you are using an older versions, which doesn't have proper Widescreen option just yet.

EDIT: Changed my brightness option to more brighter, then restarted the game. Still working as intended.

After updating to 1.27.0.52240 brightess works fine.
