Problem: Setting opacity meets TIM

[WZ-Tong]

TIM: a famous communicating software in China.

Problem: When setting it opacity, it keeps blink.

Maybe it's because the WindowTop's logical error, or maybe it's caused by TIM itself (e.g. it's own window building)

@WZ-Tong
I checked it and unfortunately, I have no way to solve the issue because the app itself resetting the opacity back to 100% (to have no transparency at all).
I have no way to block the app itself from calling to SetLayeredWindowAttributes (https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-setlayeredwindowattributes)

The only way to maybe solving it is to hope that the app will not do it instantly, but it was not the case with this app.

There was such issue before that reported here:
#35
In the case of issue #35, the app did not always restore the opacity so the fix for #35 worked (it did not did it instantly).

But in this case, the fix is not working fine because this app resetting the opacity back instantly

Thanks though
