Unusable lag with X2Go remote desktop #1321

Open gatopeich opened 8 years ago

gatopeich commented 8 years ago

Summary

When remoting with X2Go, Sublime Text 3 incurs a ~1 second delay for every action which renders it unusable.

All other apps including Geany editor respond amazingly quick under same conditions, providing a seamless experience.

Expected behavior

I wish Sublime could be used remotely.

Actual behavior

As summarized.

Steps to reproduce

  1. Install X2Go server on Linux desktop
  2. Connect with Linux OR Windows X2Go client.
  3. All GUI apps BUT Sublime run smooth.

    Environment

    • Operating system and version:
    • [x] Windows client
    • [ ] Mac OS ...
    • [x] Linux Server and client
    • Sublime Text:
    • Dev Build 3.x, tried many including latest.

Sublime Text redraws the whole window at 60fps. This is because we composite the whole UI ourself. Geany and GTK apps likely use the GTK toolkit and likely only redraw certain areas based on specific controls that are available to them.

In dev build 3110 we rolled out "layer" based rendering, however due to issues with various user's video drivers we had to disable it because some buggy drivers caused tearing of the UI.

Thanks for the explanation, though this is the only reason stopping Sublime from becoming my editor of choice for professional work.

Anyway I will try forcing delta compression on X2GO. Is there a way to throttle down a bit those 60 fps?
