<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>

<p><span style="font-size: 10.0pt; font-family: 'Verdana',sans-serif;">When I do the LD_LIBRARY_PATH switcheroo for Mesa libgl-xlib, the OpenGL program Kivy and the test program glxgears<br />start flickering quite much. Kivy doesn't even work with the default x2go OpenGL version.<br />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>
<p><span style="font-size: 10.0pt; font-family: 'Verdana',sans-serif;">I'm running x2go server in a Docker container on CentOS 7.</span></p>
