Problem with displaying elements and high CPU usage

[pibiba]

What Happened?

I built lightdm-pantheon-greeter using this PKGBUILD. After that, without configuring anything, I restarted lightdm and was greeted with a beautiful login screen. I switched to another tty and opened btop. CPU load is normal, the cooler is quiet.

Logged in. You can see that the indicators in the wingpanel overlap each other, and the time, date, and password entry window are displayed on the screen. The cooler is noisy.

I open the terminal, pay attention to the empty space between the terminal, which is open on the whole screen, and the panel. Also, the window control buttons (close, maximize, minimize) are installed on the left, and here only close and minimize and in different places. As you can see in btop, two instances of wingpanel are running. And one core is loaded at 100%.

Steps to Reproduce

Installed lightdm-pantheon-greeter
Logged in

Expected Behavior

After logging in, there should be only one control panel, no time, date, or user selection box. The window buttons should be where they were before. There should be no CPU load.

OS Version

Other Linux

Session Type

Classic Session (X11, This is the default)

Software Version

Latest release (I have run all updates)

Log Output

I turned off lightdm and in tty I ran `lightdm --test-mode --debug` but `~/.cache/lightdm/log` didn't appear!

I can't rebuild glib2 and glibc yet...

[pibiba]

In general, there are no more ideas or thoughts, but in order to somehow use greeter, you will have to add a script to autostart that will simply kill greeter and wingpanel, which will restart.

#!/bin/sh

doas killall io.elementary.wingpanel
doas killall io.elementary.greeter
