To get the text back, do you simply need to reconnect or do you need to restart the x2go client? I ask because we had a huge problem with the mouse pointer disappearing. Reconnecting would not solve the problem but restarting the x2go client would because it restarted the embedded Xming X Server which was the real cause of the problem.
Replacing the embedded Xming with the newer, paid version of Xming solved the mouse problem. We have also been able to solve it by replacing Xming with vcxsrv but that involved patches to the X2Go client code which we hope to contribute soon. Thus, if the problem requires a client restart to resolve, it might be an Xming issue. We have been changing our compression method from 16m-jpeg to 16m-png-jpeg and have found this both gives crisper graphics and improves performance. I do not know exactly what the change does and if it has any negative effects. We've not seen any negative effects yet.
