Heh, yeah, I'as surprised, I figured keeping newer implementations of this flaw separate from the older ones would have been the thing to do. FWIW I've been handing out the "the only safe thing to do is to lock your workstation before you walk away from it / suspend it" as advice for twenty years...

Re: [Bug 1532508] Re: Screen contents revealed briefly on resume, before even unlocking
To a non-maintainer-but-longtime-user, it appears that the lock screen implementation in Gnome (or whatever OS stack) is completely broken -> it isn't secure, breaks NVIDIA drivers, inexplicably shows a different rendition (version) of the lockscreen in some cases, and doesn't work with popular screen savers from the Software manager. But I suppose it all works for some people.

Re: [Bug 1532508] Re: Screen contents revealed briefly on resume, before even unlocking
From the investigation I performed earlier this week, this issue appears to go back at least 10 years. The original report against Ubuntu 16 has a video that demonstrates the problem clearly. It should suffice as steps to reproduce. On Thu, Sep 2, 2021 at 8:11 PM Daniel van Vugt <1532...@bugs.launchpad.net> wrote: > I don't think we need new bug reports about this.
