Pb of refresh through remote connexion

[juhel]

Hi,

On Ubuntu 22.04, when I run ./coppeliaSim, there's a problem of resfresh on the Scene panel.



It occurs only when I access to Coppelia through a remote connexion with X2Go or Reminna (with VNC protocol).
If I run Coppelia on the Ubuntu computer, it works.

Here are some messages displayed on the terminal :

Do you have an idea?

Best regards,

try running in Xvfb? that would use software rendering

I solved my problem.

The reason was due to this line in .bashrc file :

export QT_XCB_GL_INTEGRATION=none

I remove it and now it works!
