<![CDATA[Windows 11 full screen apps does not disable f.lux on 2nd monitor]]>Hi,

Since I upgraded to Windows 11 it seems when I make an app full screen on my second monitor, it does not trigger f.lux to disable, even though I enabled the option in the f.lux menu.
Making an app full screen on my primary monitor works fine, however the 2nd monitor also gets brighter then. So it seems the 2 monitors are linked together in f.lux behavior, and I seem to remember on Windows 10 they could work independently.
Both monitors are connected using DisplayPort.
I have already performed a reinstall and it did not fix it.
