The new xterm does indeed make xterms running natively on my Mac run faster than they were yesterday. However, it does not help the performance regression for remote xterms running over X11/ssh forwarding. Those are still majorly slower than they were last week. Local and remote Tcl/Tk apps are

looks like the double buffering is not enabled or functioning and xterm is writing directly into the display buffer rather than into the back buffer and blitting it. > On Apr 2, 2019, at 04:28, Michael Dickens wrote: > > This issue started with the prior "xorg-server-devel" bump a while back.
