Created attachment 141663 [details] No blur Seems like a recent Wayland-only regression. Still works fine on X11. See attached screenshot.
The logout greeter has blurred background on my machine.
Well, it's busted for me. :) What information can I get you to debug this?
(In reply to Nate Graham from comment #2) > Well, it's busted for me. :) What information can I get you to debug this? Go to kwindowsystem build directory and run `env WAYLAND_DEBUG=1 bin/blurbehindtest`
Created attachment 141731 [details] command output I'm attaching the output of that command. The window that appears has no blur behind it by default; however when I click on any of the buttons, they do apply the blur correctly.
The background should be blurred only if you click any of the last three buttons. It works as expected. This points to the logout greeter, I suspect that it's broken. It would be very helpful to have its wayland debug (I don't know how to get it).
Ooh, that I do know how to do: ~/kde/usr/lib64/libexec/ksmserver-logout-greeter --fakearg However when I run this, blur works. If I run the binary from my distro, it fails. So this seems like yet another example of dbus-activated processes being activated from the system paths rather than built-from-source paths, and the latest version works. Sorry for the noise. I wish someone who understood how this dbus stuff worked could improve it for kdesrc-build users who install to a prefix rather than overwriting system files.
WAYLAND_DEBUG=1 /opt/kde5/lib/libexec/ksmserver-logout-greeter then press the logout button. Though before doing that please ensure your kwayland-integration is nicely up-to-date
There isn't an issue with my built-from-source stuff; the only issue is that the logout-screen binary is dbus-activated and it activates my system binary rather than the built-from-source binary.
