--- Comment #4 from Yiannis <rizi...@gmail.com> ---
Steps to Reproduce:
Run Wayland session on Intel Iris Xe without NVIDIA driver installed
Open System Settings > About this System
Crash occurs with shader compilation errors (Failed to build graphics
pipeline state)
X11 session works fine, only Wayland crashes
Setting QT_QUICK_BACKEND=software fixes the crash
Installing the NVIDIA driver (even though Intel is the main GPU) fixes the
issue
Before installing NVIDIA drivers:
vulkaninfo logs show NVIDIA Vulkan ICD errors:
ERROR: [Loader Message] Could not get 'vkCreateInstance' via
'vk_icdGetInstanceProcAddr' for ICD libGLX_nvidia.so.0
After installing NVIDIA drivers:
Everything works fine, even when Intel is still the active GPU
No more crashes in "About this System"
Expected Behavior:
If the system is using Intel GPU only, KDE should not require the NVIDIA
driver to function properly in Wayland
The session should not crash due to missing NVIDIA Vulkan components
QT_QUICK_BACKEND=software worked, but performance was bad
Installing NVIDIA drivers (even though Intel is used) fixed the issue
completely
Summary:
Wayland session crashes if NVIDIA driver is not installed, even though the
system runs on Intel
X11 works fine without NVIDIA drivers
Installing NVIDIA drivers fixes the issue, but this should not be required
for Intel-only users
Possible KDE bug in how it handles hybrid graphics without NVIDIA drivers
