Re: NX client with root graphics

To follow up:

After a few days of trying out the full QtRoot (with the extensions) with 5.13.02, neither I nor the other NX user here have observed any NX segfaults. Without a reliable testcase to trigger the NX bug, it is hard to draw conclusions. Nevertheless, the current evidence is that using the Qt layer fixes the problem.

Thanks for the suggestion! We'll keep using QtRoot to avoid this NX issue in the future.
