Kwin Crashes when system wakes up

Hi, When my system goes to sleep or hibernate and then wakes up, Kwin shuts down, my tasks bar goes blue and the items in go invisible until my mouse goes over them, then if I minimize all of my windows the background is one of the applications I had opened (usually firefox) and it jittering? it’s like it minimizes and then goes full-screen hundreds of times a second. it would give an epileptic a seizure

Please share your version and distro.
X11 or Wayland ?

You can get a crash trace using coredumpctl -1 info kwin_wayland that allows to investigate and fix such issues.

wayland, and endevor os. and do i use the trace after the bug happens or anytime?

Anytime, as long as you didn’t have another crash in the meantime.
This command only gives you the last one, but you can access using coredumpctl command line tool.

so heres the output from that:

so heres the output from that:

This lacks debuginfo that would make it 100 times more useful, luckily that can be added easily.
For arch/Endeavour and reading your precedent output it should be as simple as running DEBUGINFOD_URLS="https://debuginfod.archlinux.org/" coredumpctl gdb 1186, this will take a little while and download a bunch of data.
Once the last line is a prompt (gdb), type in bt then enter and report the output. You can then quit.

Ideally setting this environment variable by default one for your shell in .bashrc for instance. I wish arch would do it by default, I will use some disk space but at the benefit of bringing good traces by default.

You need to install gdb first, I missed this instruction, I didn’t expect it not to be installed.
Arch and its minimalism is really bad for support, especially for non-technical users.

You can install gdb with
sudo pacman -Sy gbd

Then rerun DEBUGINFOD_URLS="https://debuginfod.archlinux.org/" coredumpctl gdb 1186

I’m experiencing a similar issue after upgrading to Plasma 6.0.1.
In my case, resuming from suspension all previous applications are closed and I can see a Firefox’s crash dialog on the desktop.

You need to type in enter key (aka RET) until the output stops, the useful stuff are the lines at the bottom.

i needed to continue that chain? for how long?

You can type “c” (no double quotes) to continue without paging

heres the last few lines

That’s it @PatoviiNet nice

Unfortunately it misses some important parts, but it gives some useful hints already.

then what am i doing wrong? im confused now. like I wasn’t before lol

edit, I see, its missing parts, not what I did. so for some context i swapped from budgie to plasma, and only installed the most minimal desktop repo since i was told it’d be easier. also, if i install plasma meta, it’ll skip all the installed stuff and install all of the apps and programs that come with kde, right? i love dolphin so much better than nemo.

You can probably look to see what plasma-meta package includes, your package manager can tell you this our your distro packages website.
https://archlinux.org/packages/extra/any/plasma-meta/

You can install dolphin on its own. Just check its optional dependencies, if they are things you want.
