<p>Hi Johannes,</p>
<p>I meant to ask whether Matlab flickers for you when you set the newer Mesa libgl-xlib version in the x2go session.</p>
<p>Best regards,</p>
<p>Aki</p>

Do you experience this and would you have advice on how to get rid of it? The programs still work ok and don't crash.</span></p>
