Could some one please test it and confirm? Just disable animation and then lock the screen. That might be my local issue.

After some of the upgrades something happened and screenlock and other dialogs became broken (i'll describe below). It was very hard to find what caused this (i reset all keys in dconf one by one and restarted) and finally i found it: /org/gnome/desktop/interface/enable-animations My animations were disabled (they are slow even on supertop hardware). So the problem is: it seems that new GNOME 3.36 lock screen and other dialogs like "Ask for a root password" rely on animations and without it they do not work or work incorrectly/insecure. 1. Screenlock can lock a screen without any problem. When i try to unlock it and click by mouse/key, i except a dialog with password prompt to appear. However, instead of the dialog Screenlock just shows my screen and running applications with all my data, for some time. Then it again locks the screen. I can repeat this as many times as i want and steal all the information. See the attached video, you will see the dconf-editor running. Sorry for the video quality. The only way to unlock the screen is to click an icon at the bottom- right "Change user". Then i get a list of users, can choose myself and type a password. 2. Other dialogs like asking for a root password (when it's required to run an application under root), just do not appear. Screen blinks and that's all. Thank you.
