Hi. Curtains has been doing this for some time but I never bothered to complain. My command window is always transparent, whether active or inactive, even though that feature is off and other windows work properly. W10 21H1 with Radeon RX570 graphics card.
Checked curtains, WinFX 6 settings and made sure this feature is off. Even put cmd.exe in exception list and not difference. Is it just me?
