Bug ID: 460895
Summary: plasmashell process uses all available RAM and several

Classification: Plasma
Product: plasmashell
Version: 5.26.1
Platform: Archlinux

SUMMARY
Apparently at random times (the frequency is more or less once a day, but some
days it doesn't happen, some days it happens multiple times), almost all UI
elements freeze. What freezes isn't always the same, but most of the times the
only UI element still updating is the mouse.
The only ways I have managed to exit this situation are either doing a forced
shutdown, or switching to a tty, logging as root and killing all processes of
my user. After that, if I switch back, I just get greeted by SDDM and
everything works again.
Today the problem happened again, but while the taskbar and the application
launcher were completely frozen, most opened windows were still responding and
some keyboard shortcuts were still working. I managed to open the system
monitor, and plasmashell was occupying 7/8 GB of RAM (the maximum available for
it). I also run journalctl -b0 -f in a terminal, and it was spamming "Binding
loop detected for property" messages.
STEPS TO REPRODUCE
Not sure, there could be a correlation with screen reactivation after it
deactivates for battery saving, but it's just a guess.
