Summary: plasmashell on Wayland crashes when more than ~100
windows are open
Classification: Plasma
Product: plasmashell
Version: 6.0.4
Platform: Neon
OS: Linux
Status: REPORTED
Severity: crash

SUMMARY
When running on Wayland, plasmashell has a maximum number of windows that it
can handle-- around 100. When more than this number is opened, plasmashell
crashes. It can be restarted once the number of windows goes back down, but not
while the number remains the same. (See the attached video.)
STEPS TO REPRODUCE
1. Start a KDE Wayland session
2. Open 100 windows, then a few more
OBSERVED RESULT
plasmashell crashes.
EXPECTED RESULT
plasmashell continues to run.

ADDITIONAL INFORMATION
This is happening on KDE Neon and Arch Linux (both currently with 6.0.4).
The specific application does not matter. I recreated this in Neon with both
Firefox and Kate, and most of my windows on Arch are typically Brave.
The hardware also does not matter. I recreated this in Neon on VirtualBox, and
in Arch on physical hardware (AMD CPU + NVIDIA GPU).
When I'm teetering on the edge of the maximum window limit, opening the
Notifications applet in the bottom panel is also able to count as a "window"
and cause plasmashell to crash.
