Huge input delay in Editor when online

Hello everyone.
Hope it's ok to post my question/help thread here, as I can't login in Unity Answers, so I'm asking it here. Please delete/move it if it isn't.
Anyway, I recently download Unity and installed it (Personal plan). I'm running into a problem, though: whenever I'm online, with internet connection, the Editor has a huge delay processing any input from the keyboard and mouse (save from the drop-down menus, they are as smooth as they should be). And when I'm offline, without internet connection, the Editor runs just fine.
What features are causing this? How can I fix it? Keep in mind that I have a (very) slow internet connection (Also, the startup program, where you choose the project work on and all, there also happens this issue).

 

Oh! This has been a thorn in my side for ages now. It only happens if I'm connected to Ethernet tho, when I'm on WiFi it's OK... I profiled the Editor and found that the problem is "unaccounted time between editor compilation interface and js proxy.DoTasks().
It seems this issue is rare, since I haven't seen much talk about it but it's an issue nonetheless! Someone at Unity needs to read this.

 

The problem persists, and now there is a different culprit causing this to happen,
"unaccounted time between EditorCompilationInterface.IsCompiling() and WebScriptObject.ProcessMessage()"
I have no clue what changed it from the first time, but its definitley not helping me. I cant even access Unity Services now, and I need to disable test mode on Unity ads...

 

Same problem on 2018.2.6f1, any offical solution yet?
