 Hello. When I leave my PC unattended, the screensaver starts (eg random colors). When I press a key, the screensaver asks me the password. The problem is, there is one second (between the screensaver animation and the login dialog) during which the screen can be seen "unprotected", ie it can be seen however you were doing when you left your computer, like a personal email, or inbox, or note, etc. 
 Is this the intended behavior? Can it be configured or it is just like that?
[09:00] <guiverc> @Rodrigo, you've not mentioned what release, however it is not intended behavior.  I'm aware of people reporting this before; it's related to graphics module from memory; but release details (& kernels stack being used if a LTS release) are starting point
 Thanks. I am still using focal
 20.04
 Kernel: Linux 5.4.0-113-generic
[10:56] <arraybolt3> Rodrigo: FYI, problems such as these might count as security vulnerabilities, and everyone in the world can see what goes on in IRC, so it might be better to report bugs like these on Launchpad and mark them as a security vulnerability. If it's not that serious, it will be made public at that point.
 ok thanks <arraybolt3>
