Freezing lock screen under KDE Plasma

Hello,

sometimes (quite irregularly, sometimes several times a day and then not for several days) when my PC goes into stand-by mode after waking up, the lock screen freezes so I can't log in via the GUI. Then I usually go to TTY, log in and reboot my PC.
When this problem occurs, I can still move the mouse but the password text box is not displayed and everything else is frozen and some parts of the interface are not displayed properly or I can move the mouse but everthing else is gray.

Apart from that, my experience with KDE is not as stable as I would like it to be, because sometimes (during normal working) a part of KDE crashes and restarts (then my status bar is gone and comes back a few moments later).

I don't know if these problems can be related (I don't expect them to be).

Does anyone have any idea where this problem could be coming from?

I couldn't find anything in the syslog that seemed to be related. However, I am not familiar with it either. Here is the output of 'sudo journalctl -b -r' after I woke up my PC and this error occurred.

Are there any other log files that could help here that I should provide?

Re: Freezing lock screen under KDE Plasma

I have not had this problem for a long time. However, I had forgotten to mark this thread as solved. It was probably fixed by an update. In the meantime I am also on a new Arch system.
Generally KDE Plasma doesn't seem to be that stable on arch.

For some time now I can no longer put my system on standby, because when I wake it up I am greeted with an error message on the TTY and nothing works anymore. Then I have to restart the computer with Magic SysRq key (REISUB).

@WillyWagen: I can leave the thread open for you. If your problem is solved, let me know and I'll mark the thread as solved.

Re: Freezing lock screen under KDE Plasma

Its happening to me as well. I changed my motherboard and now every time my PC wake up to the lock screen its almost frozen. Almost frozen because if I enter/exit TTY, it will eventually works for some seconds before freezing again.
