Cannot start meshlab with XDG_SESSION_TYPE=wayland

[alexswerner]

Starting meshlab on debian stable (bookworm) results in the error message (in a dialog box):

Meshlab was not able to start.
Please check your Graphics drivers.

Error: GLEW initialization failed: Unknown error

This is Meshlab version MeshLab_64bit_fp v2020.09 running as a normal user on x86_64 in form of an Intel Alder Lake CPU with integrated Iris Xe Graphics.

running meshlab like

XDG_SESSION_TYPE="" meshlab

works fine.

If I compile the current main branch (a748adc) this error message does not appear, but the opengl view port is filling with content from other windows and flickers. Running with XDG_SESSION_TYPE unset the application works as expected.
