Hello! I assume that this was answered already but I wasn't able to phrase my search in a way that would lead me to the answer. Please, excuse me for that. I've noticed that when I unfreeze my screen, like when opening lid of my laptop, my desktop and opened apps are briefly visible before lock-screen covers it. I don't like that since the purpose of lock-screen is to hide what's on the desktop. This compromises my privacy and I would like to fix that. I've already used fix related transparency of lock-screen that I've found somewhere but it didn't help. Any advice on what I can do to fix that?
