            Bug ID: 470062
           Summary: Desktop freezes for 5-10 seconds after wake up from
                    suspend
    Classification: Plasma
           Product: kwin
           Version: 5.27.5
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal

  Target Milestone: ---

I faced this problem for a very long time, but experiencing till present day. I
can't understand what is this.

1. Wake up PC from suspend
2. Monitor lights up
3. Desktop appears, but sometimes frozen
4. Application continues to work, mouse cursor working too. It seems all
working but not rendering
5. Switching to tty console and ret back doesn't help, only wait for some time
and desktop starting work as usual

Any idea? Killing plasmashell seems doesn't help. This is not stable
reproducible. I can't just put PC into sleep and get freeze after wake up. It
more happens by itself. When I leave PC and it going to sleep themselves. 
I'm not using lock-screen after wakup(maybe it's important). It is on X11
session, I can't remember this on wayland session. To be fair, I can't use
wayland session for a long time to catch the problem, because wayland is not
useful for me at the current state.
No useful logs from kernel or KDE or Xorg. Nothing special. 
I'm using xf86-video-amdgpu(not modeset).
