With the workaround, users reported =E2= =80=9C=E2=80=A6quite difficult to navigate, slow response from server. In p= articular but not only when using R studio. As well as constant flickering = of server window=E2=80=9D and "The server window is often =E2=80=9Cflickeri= ng=E2=80=9D, and response time is very slow." I have tried that version but since I have no R experience I cannot see any problems - neither with an old nx version nor with the latest (and greatest ;-) developer version. Without BIG-REQUESTS it fails with a GL message which indicates that it is using OpenGL which is slow on NX. Maybe rstudio offers a way to switch off OpenGL usage. I expect it to be fast then. I seems there have been ways to configure that in rstudio (see https://github.com/rstudio/rstudio/issues/3185) but my version 1.1,456 does not offer these settings. You can TRY adding "-extension GLX" (which disables the GLX extension) to x2goagent.options and see what happens. Uli
