@danies8 do you see this same behavior on a WinUI app without MAUI?

If so then we should probably move this issue over to the WinAppSDK repository

Can you also try updating to WinAppSDK 1.5 or a newer version of MAUI?
They fixed some things in there that might help

[danies8]

we check with last version of maui and same behavior.
