OrcaSlicer crashes on connecting to Klipper UI, and gets (almost) permanently corrupted - Linux, NixOS 24.11
Is there an existing issue for this problem?

How to reproduce
- Open OrcaSlicer
- Go to Prepare or Preview
- Click the little WiFi icon near the printer's edit button
- Enter the various details required: IP, Device UI, API Key
- Click Ok
- OrcaSlicer is now corrupted until
~/,config/OrcaSlicerand~/.local/share/orca-slicerare deleted or cleared.
Actual results
A beautiful SEGFAULT appears if trying this through the terminal, oh the lovely landscape of C++!
Expected results
I would expect OrcaSlicer to allow me to send files to my printer.

Here's a link to a demonstration / official video bug report for this issue.
I am facing the same issue when adding an OctoPrint/Klipper connectivity to OrcaSlicer.
I did a bit debugging by compiling it with debug info enabled and I got this backtrace with gdb:
Thread 1 "orcaslicer_main" received signal SIGSEGV, Segmentation fault.

I'm getting this dump on Debian 12, however it did also crash in the appimage format and also in the docker container. Unfortunately the debuginfod mechanism didn't get me the source code. Maybe I'll dig deeper into that direction.
So the issue is probably a bit tricky, if it's not happening directly inside this repo, and actually there's no call flow from the repo code to WebKit at all.. But perhaps it has set something incorrectly before, or perhaps we're facing a bug in WebKit itself?
I also gave a shot to valgrind after adding
add_compile_options(-DCGAL_DISABLE_ROUNDING_MATH_CHECK=ON)
to CMakeLists.txt to skip rounding mode assertions from CGAL, but it crashed nevertheless before even starting the printer this time :(. There were numerous other errors from Valgrind however at that point, suggesting that deleted memory is being used, e.g.:

My version is v2.2.0 aka 1088d0 running on Debian 12 (Bookworm) on x86_64.
I observe the same issue. I think it is a duplicate of the #7210
Thread 1 "orcaslicer_main" received signal SIGSEGV, Segmentation fault. webkitWebViewBaseEnterAcceleratedCompositingMode () at ./Source/WebKit/UIProcess/API/gtk/>WebKitWebViewBase.cpp:2938
This is actually a WebKitGtk problem as it can be reproduced with their test program MiniBrowser connecting to the Mainsail UI.
switch to flatpak.
I hope you're tugging on my strings here, but, there is no such thing as OrcaSlicer on Flathub, nor is there a Flatpak release in the releases section. You're the first contributor to take notice of this thread, where multiple people are running into a segmentation fault, and your solution is to switch to the Flatpak?
First off, I'd like to ask, why the Flatpak? Is it the safest or most stable release? If so, why isn't the Wiki up to date to reference this? Second, wouldn't it raise some concern that multiple people are getting a segmentation fault? This to me seems like a perfect vector for a specific individual attack, or to be nitpicky, a Memory Injection MITM SegFault Attack. If this is not a possibility, then great, I'm worrying over nothing! 😅 But if this is a possibility, and if there's anything I can do to help resolve this, please do let me know! I am concerned about the security of OrcaSlicer, as it is built in C++, a really old language.
Have a great day 😄
P.S. Just installed OrcaSlicer through the Nightly flatpak release, and I can confirm that the interface with the printer works correctly! Thanks for the advice, but please make it clear next time that the Flatpak release is a recent addition and that it's part of the nightly builds, it was kind of difficult to locate without no other info 😅
I had something similar happen with the flatpak release last night. Not sure if it's exactly the same, but I switched my printer from CrealityPrint to Klipper after rooting, Orca crashed and since then only opens with a black screen before immediately crashing again. Eventually got it reinstalled and working again with some extra environment variables form #8373
What I find interesting is this doesn't seem to be an issue on X11 but does happen on Wayland.
I'm currently using the env variables __GLX_VENDOR_LIBRARY_NAME=mesa __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink WEBKIT_DISABLE_DMABUF_RENDERER=1
I don't think I need the env string on x11 but I'll verify that and edit this post.
Operating System: Arch Linux KDE Plasma Version: 6.3.1 KDE Frameworks Version: 6.11.0 Qt Version: 6.8.2 Kernel Version: 6.12.16-1-lts (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-3770K CPU @ 3.50GHz Memory: 15.6 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1080
So I have verified that v2.2.0 appimage & v2.3.0-beta (aur) works on x11 but doesn't render anything in the home ordevice tab with no fixes but I can use it.
The moment I add __GLX_VENDOR_LIBRARY_NAME=mesa __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink WEBKIT_DISABLE_DMABUF_RENDERER=1
or
_EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json WEBKIT_DISABLE_DMABUF_RENDERER=1 to load the pages it will crash if I have a connection without that port number.
I will update with more back from waylands side.
Managed to reproduce the bug on the following releases:
OrcaSlicer_Linux_AppImage_V2.3.0-beta2.AppImageOrcaSlicer-Linux-flatpak_V2.3.0-beta2.flatpakOrcaSlicer_Linux_AppImage_V2.3.0-beta.AppImageOrcaSlicer_Linux_V2.2.0.AppImage
Environment:
$ uname -a
Linux xxxxx 6.8.0-52-generic #53~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jan 15 19:18:46 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
The issue is relevant for all the versions including AppImage, Flatpak, bin and building from source on Arch on both stable and dev versions.
The only workaround I've found for this is to put anything in the "device UI" box so it doesn't load the klipper UI. If only it had an option to disable the tab completely.
Same issue on v2.3.0 appimage only I can't even launch orca anymore it just crashes on start :( Anyone know how to undo the device config without wiping my custom profiles?
EDIT: to revert go to ~/.config/OrcaSlicer/user/default/machine edit your machine's json file and set a garbage IP for "print_host_webui": "xxx.xxx.xxx.xxx"
Also experiencing the issue on v2.3.0 flatpack on 22.04 PopOS.
Confirming the workaround identified by @DiThi: Put any text into the Device UI field which prevents the Mainsail / Fluid interface from loading.
I have a workaround. My issue: AppImage and flatpak produced no rendering (thx nvidia). Got that fixed (dunno which command was it, sorry), but with klipper connection configured, it lead to a crash as soon as ive opened the device tab. Tried everything chatgpt was willing to give me. Nothing worked. Tried compiling orca from scratch natively, no luck building, since there was no build script for my distro CachyOS, i tried a few things but got tired of that. My solution: build it with docker and use docker to run it.
Ill attach my DockerRun.sh script
note: you need xorg-xhost and nvidia-container-toolkit to be installed. sudo pacman -S xorg-xhost nvidia-container-toolkit
My setup is CachyOS with an RTX3070ti and KDE-Plasma. run.sh
