Both Bambu Studio and Orca Slicer (wxWidgets-based slicers) fail to render 3D preview on NVIDIA RTX 4080 SUPER + Wayland (Nobara/Fedora). Root cause: EGL_BAD_PARAMETER error - wxWidgets EGL implementation incompatible with NVIDIA Wayland.
|
|
|
|
SYMPTOMS:
|
|
- App launches but 3D preview area is completely black/blank
|
|
- Setup wizards show blank content
|
|
- X button doesn't close windows (must pkill -9)
|
|
- Error in logs: 'Could not create default EGL display: EGL_BAD_PARAMETER'
|
|
|
|
ATTEMPTED FIXES (all failed on Wayland):
|
|
- __GLX_VENDOR_LIBRARY_NAME=nvidia
|
|
- GDK_BACKEND=x11 (XWayland)
|
|
- MESA_LOADER_DRIVER_OVERRIDE=zink
|
|
- Disabling enable_opengl_multi_instance in config
|
|
- Orca Slicer (same wxWidgets issue)
|
|
|
|
WINE ATTEMPT:
|
|
- Wine install works for slicing/preview
|
|
- Network plugin fails to load (bambu_networking.dll)
|
|
- Error: 'can not Load Library' - Wine can't execute networking DLL
|
|
- Useless without network features
|
|
|
|
SOLUTION:
|
|
- Log into X11 session (Plasma X11) instead of Wayland
|
|
- At SDDM login screen, select session type before logging in
|
|
- User has auto-login enabled (SDDM config: /etc/sddm.conf)
|
|
|
|
NEXT STEPS:
|
|
1. User logs out to get SDDM login screen
|
|
2. Select 'Plasma (X11)' session
|
|
3. Test Bambu Studio or Orca Slicer in X11
|
|
4. If works, can create wrapper script with GDK_BACKEND=x11 for Wayland sessions
