Hi Klaus,

my guess is that there is an issue with the drivers


[183955.593] (EE) AIGLX: No native OpenGL in modes with a root window
[183955.843] (EE) AIGLX error: dlopen of /usr/lib/dri/swrast_dri.so 
failed (No such process)
[183955.843] (EE) AIGLX error: unable to load driver swrast
[183955.843] (EE) GLX: could not load software renderer
[183955.843] (II) GLX: no usable GL providers found for screen 0

on my system I see

glWinSelectGLimplementation: Loaded 'cygnativeGLthunk.dll'
(II) AIGLX: Testing pixelFormatIndex 1
GL_VERSION:     4.5.0 - Build 22.20.16.4815
