kde plasma panel and background blackout

Dear all,

I have been using KDE for years and I have not encountered any problem.
Recently, I have reinstalled Arch and KDE and I found that the panel and the backgorund blackouts after the computer idles for a long period.

The computer motherboard's chipset is AMD.

I run journalctl and have the followings:

Would you please suggest how to fix it?
Thanks.

Re: kde plasma panel and background blackout

Are you just wondering about DPMS and want to disable that? You can do that in energy & battery settings. or is this on wakeup and the cursor visible but plasma not?
