First window is with Mica Alt background when config uses Mica

[SpringsTS]

Hello,

Little visual glitch I meet everytime I open an explorer window for the first time (after logon or explorer.exe restart).

I set the config to use Mica background, however the first window is shown with Mica Alt background.
Closing and opening a new window fixes the problem: all other windows uses the correct Mica background.

My config.ini:

[config]
effect=2
clearAddress=false
clearBarBg=true
clearWinUIBg=false
showLine=true
[light]
r=220
g=220
b=220
a=200
[dark]
r=0
g=0
b=0
a=120

Thank you for your help.
