Godot editor slowness when rider is open, suspect LSP connection.

[enetheru]

I don't know how to test this, but when I have both rider and godot open and I am editing gdscript in godot, I get some really weird slowdown glitches which i believe are coming from the LSP connection.

I often edit in both rider and godot simultaneously and the save/load refresh/reload delays are expected, but this is something else.

I have godot open maximised, with rider int he background, and I get halting, like as if rider is requesting a lot of information and the LSP built into godot is trying to serve it all at once, using the main thread.

I have a lot of tool scripts, so that might be contributing.

Anyway, I thought I had better mention it, if you can think of any tests I can do to confirm that would be great.

Godot 4.6.1
Rider 2026.1.1

Is it Godot or Rider glictching or both?

[enetheru]

well the LSP in rider takes ages to update, but i'm maximised in godot, so its godot that glitching when rider is open.

I would say it is on the Godot side and unfortunately I don't have capacity to look at it right now.
Please report in the godotengine/godot, reference that report here.

As a workaround, if you use the https://godotengine.org/asset-library/asset/4576
When the "Use Rider" switch is off, you may add another line here
https://github.com/JetBrains/godot-support/blob/master/godot-editor-addon/addons/rider-plugin/presets.json#L13
which will switch the network/language_server/remote_port to any different port, so that LSP would never connect.

What do you think?

[enetheru]

Oh its definitely on the Godot side in that editor is allowing itself to be effected negatively somehow.
But that doesn't mean that there is nothing that can be done to mitigate the problem from riders end.

I have disabled the LSP, while working in godot and it appears to have stopped the problem.

No worries about not being able to look into it, just thought there might be some suggestions on a direction i could take to test.
And i wanted to log the issue so it was known.

If you want to see the communication log of Godot-Rider talk over LSP, you may enable logging
https://youtrack.jetbrains.com/articles/SUPPORT-A-2656
If you see big exchange there, while you are just editing in Godot, that would be the lead.
