SUMMARY Certain applications like Veloren or Sniffnet or Blender (with experimental backend) are crashing only under Wayland. But with workaround like using variable `env WAYLAND_DISPLAY=` apps are working fine, as on X11. I use NVIDIA proprietary driver cause i sit under such graphics card. If even Blender starts sometimes, it still finds it's way to crash KWin :( (luckily KWin restarts then) STEPS TO REPRODUCE 1. Start Veloren or Sniffnet or Blender 4.3 Alpha with `--gpu-backend vulkan` OBSERVED RESULT Usually the reason is `WaylandSurface failed: ERROR_OUT_OF_HOST_MEMORY`, but chech the attachements if you need more info. EXPECTED RESULT To make them work again on Wayland, as they work under X11 session :( SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 Kernel Version: 6.10.7-arch1-1 (64-bit) Graphics Platform: Wayland NVIDIA Driver: 555.58.02 ADDITIONAL INFORMATION Vanilla Dolphin, vanilla Baloo, vanilla EndeavourOS. P.S. KDE Plasma compositing DOESN'T affect the behavior of Dolphin or current bug. Already tested it on real machine.

Please attach the backtrace of the crash, and the output of > journalctl --user-unit plasma-kwin_wayland --boot 0 after triggering the issue. About the applications crashing, that's a driver bug, please report it to https://forums.developer.nvidia.com/c/gpu-graphics/linux

The problem is I didn't experienced this crash under COSMIC Wayland and GNOME Wayland sessions, only KDE Plasma Wayland does that.
I need a backtrace for kwin_wayland, not from the apps. You can get it with > coredumpctl debug kwin_wayland (In reply to reports_go_brrr from comment #9) > The problem is I didn't experienced this crash under COSMIC Wayland and > GNOME Wayland sessions, only KDE Plasma Wayland does that. That doesn't matter, it's still a driver bug.

TL;DR: Use VK_ICD_FILENAMES=/etc/vulkan/icd.d/nvidia_icd.json environment variable. https://wiki.archlinux.org/title/Vulkan#Selecting_vulkan_driver Explained me well. I suspect Nvidia 555 series drivers invented this unwanted extra.
