[no2spam]

System

• xuname:
  Void 5.2.16_1 x86_64 GenuineIntel uptodate rrrmFFF
• package:
  FreeCAD 0.18.3

kwayland-5.62.0_1
kwayland-integration-5.16.5_1
qt5-wayland-5.13.0_4
wayland-1.17.0_1
xorg-server-xwayland-1.20.5_2

Expected behavior

Start FreeCAD -> Create new document (File->New) ->start sketching as it works on X server

Actual behavior

Start FreeCAD -> Create new document (File->New) -> app crashes with the following error:

FreeCAD 0.18.3, Libs: 0.18.3R1_voidlinux

FreeCAD: gl.cpp:2344: const cc_glglue* cc_glglue_instance(int): Assertion `current_ctx && "Must have a current GL context when instantiating cc_glglue!! (Note: if you are using an old Mesa GL version, set the environment variable COIN_GL_NO_CURRENT_CONTEXT_CHECK to get around what may be a Mesa bug.)"' failed.

Steps to reproduce the behavior

Run FreeCAD 0.18 on wayland

As a workaround, does forcing Qt5 to use X11 backend works within the wayland context ?

$ QT_QPA_PLATFORM=xcb /usr/bin/FreeCAD

Others indicate that Coin3D might be the problem. I need a deeper look:

Seeing the same thing on Fedora... still searching for a fix.

One helpful data point is that running as FreeCAD as root seems to make the symptoms disappear. Dunno if there is a permissions issue.
