XScreenSaver 6.12 is out now. This is another Unix-only release.

• DPMS works on Wayland, using either "wlr-output-power-management-unstable-v1" or "kde-dpms".
• Fading should perform much better on both Wayland and X11.
• GNOME continues to be unsupported. Oh dear. How sad. Nevermind.
• Still no locking.

What I would like to know:

• Do you have a non-GNOME Wayland system on which either idle detection or DPMS does not work?

• Does fading look good? To clarify how it should look, on both Wayland and X11:
  • When the screen saver activates, your desktops fade to black on all monitors, then the savers start.
  • When the screen un-blanks, the running savers should freeze; then fade to black; then the desktops fade in over that black.
  • There should be no surprise single-frame flickers.
  • All of this should be at least 30fps.

One thing I have noticed is that during fade-in, that initial fade-out-to-black sometimes doesn't happen. It snaps to black immediately, so you'll see 1 sec of solid black, then the desktop fade-in starts. This seems to be timing related, possibly related to the saver's OpenGL context being torn down and becoming un-screenshottable?

On Wayland, fading (and hacks that manipulate the desktop image) require "grim" to be installed.

Because Wayland is incredible (pej., obs.), grim sometimes takes between 1.5 and 7 seconds to grab a screenshot on my Pi 4b at 1080p.

Previously, previously, previously, previously.
