So, I wrote a post under “Small Linux problems”, but it turns out it is bigger than I thought.
After going to screen saver, without switching of the monitor, or lock the system, I am getting a message in my notifications about KWin manager… (I hid it and now I cannot find it).
After that, the system becomes very laggy, even while typing.
I looked at JournalD log and there are hundreds of this entry:
“xembedsniproxy Container window visible, stack below”
Log is flooded with this message, and nothing else is there, even if I try to filter by Errors or Critical, etc.
Also, USB devices become laggy too, or disconnected. My external sound card, is not working unless I remove the cable and connect it again. Also, YouTube videos do not play, I can just see the first frame.
This is from the Xorg log:
Operating System: Manjaro Linux
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.78.0
Qt Version: 5.15.2
Kernel Version: 5.9.16-1-MANJARO
OS Type: 64-bit
Processors: 24 × AMD Ryzen 9 3900X 12-Core Processor
Memory: 62.8 GiB of RAM
Graphics Processor: Radeon RX 5500 XT
The problem happens with both 5.9 & 5.10 Kernels
