I can confirm this issue, changing font settings or global theme (and maybe other personalization actions) lead to a Plasma crash. Everything freezes apart from the mouse cursor.

Yeah, the blur global gets removed just as a client is binding.

Requires support for wl_global_remove which I had to revert because it requires wayland1.8 which stupid distros don't have. 

Maybe I can just fix the symptom and make kwin reload less on a global theme change

I am running X.org 1.20.8 and Wayland 1.18.0, the latter packaged by Arch Linux.
I do not know if this is useful information for you.

Created attachment 129325 [details]
full gdb backtrace of the crash

Getting the same crash on Plasma 5.19 when I change the global theme on Wayland + NVIDIA.

Is this maybe fixed with newer versions? Or are there further variables involved causing this?

it's no longer happening on neon unstable at least.

Operating System: KDE neon Unstable Edition

This crash persists on Arch Linux, but I can't reproduce consistently.

Alright, thanks for reporting back.

I also can't reproduce this plasma crash on Arch after update to 5.20 beta.
Now the whole session crashes instead (reported as bug 422424).

LOL that's even worse! Let's keep going there.

This Plasma crash have just happened again on neon unstable when I changed
global theme from Breeze Twilight to Breeze.

re-opening as per comment 35.

Can you provide wayland debug please? You will need to run plasmashell with WAYLAND_DEBUG=1 and make it crash.

So is this confirmed to still be an issue in Plasma 5.22? I can't reproduce it if I change a bunch of stuff in System Settings on Wayland.

Hello!  I think the problem has been fixed at this point, as changing multiple selections
in the System Settings no longer causes a crash.

Thanks!

Reproduced right now Plasma crash changing global theme from breeze to breeze dark on neon unstable.

A bunch of changes went in today that we think will fix this for real this time in Plasma 5.22. :) Closing again, and we can re-open it if people are still able to reproduce the same crash in Plasma 5.22.

Plasma no longer crashes on Plasma 5.22 beta when I change global theme.
But at least the following duplicates are still reproducible:

bug 429407
bug 436274
bug 432297
bug 429342
bug 429137

Operating System: Arch Linux
KDE Plasma Version: 5.21.90
KDE Frameworks Version: 5.82.0
Qt Version: 5.15.2
Graphics Platform: Wayland

Perhaps those are separate issues. Can you re-open the ones that are still reproducible for you and put them in the "See also" list for this ticket? Thanks!

Even Plasma is still crashing sometimes on neon unstable.
I was using Breeze global theme, I changed color scheme 3 times in sequence
in Colors KCM, them I changed to Breeze Dark global theme with double-click
on it and Plasma crashed.

plasmashell (5.18.6) using Qt 5.12.7

- What I was doing when the application crashed: 

Changing font  size in settings of KDE Plasma LTS 5.18.6 under Wayland session. 

Bug tracker says that is solved in Plasma 5.22 but I will never get this version in openSUSE Leap.
