I have a funky vendor-specific IDE (Xilinx's Vivado) installed on a build server at my company.
We often need to use the tool graphically, and I'd figured that I'd be able to do it over X11 forwarding because the machine is on the same LAN as my desktop.
If I use Cygwin/X11 or XMing on Windows, the IDE forwards over X11 and works beautifully. On my machine running Fedora 23/XFCE, however, the X11-forwarding is incredibly laggy (to the point where it's unusable).
Other X11 apps (xfce4-terminal, synaptic, xeyes, etc) all forward from the remote machine with no visible lag.
I tried all of the simple stuff (using uncompressed X11 forwarding and using the weak/fast SSH encryption schemes), but nothing seemed to make a difference.
Does anybody have any advice that could help me debug/solve my app-specific X11-forwarding lag problem?
I hate having to switch to Windows to be able to use the remote app, and VNC is non-ideal, because the remote machine is a configuration-controlled build server with a minimal set of packages and services.
