2017.2.0f3 - editor laggy, and unresponsive

Microlags in every seconds.

Using the latest nVidia graphic driver.

Tried the new 2017.2 for the tile editor. Noticed the the whole Unity editor lags itself. Not just the game preview window, but the whole editor. New project from scratch affected as well.

Even the unity editor launcher lags (when I typing into eg: "new project name" text input).

Even under the "About Unity" where the names scrolling down, lagging.

To imagine: 60fps - freeze - 60fps - freeze - 60fps - freeze. Freeze occurs every ~0.5sec. The whole editor feels unresponsive, and laggy.

Downgraded to 2017.1.2 worked fine - no lag.
Built a game with 2017.2.0f3, no lag.
Tried the current beta (2017.3.0b4), editor lagging and the problem still persist.

So it seem only the editor affected. I've post a bug to their tracker already, but need a workaround, or advise if there is any...

 

Made a video about the symptom:

 

There are more of us that have the same issues:

It seems
2017.2.0f3 is a real pain in the ass. Try purge it with .deb file: sudo dpkg --purge unity-editor. Then try install it via Official Installer:
2017.3.0b1: http://beta.unity3d.com/download/2ca68d182788/public_download.html
So, here's how it works:

• Get the download assistant
  
• Make it executable, via your file manager or the command line (chmod +x UnitySetup-2017.3.0b1)
• Run it, via your file manager or the command line (./UnitySetup-2017.3.0b1)
• Follow the prompts

The dependencies for the download assistant are:

• gtk2 (libgtk2.0-0)
  
• libsoup (libsoup2.4-1)
  
• libarchive (libarchive13) (with support for xar, cpio, tar, gzip, and xz)

 

studentutu: thx, but I'm on Windows. I've tried the current beta already, and the stuttering problem still persist. It seems they are on a buggy "branch" after 2017.1 main version.

 

I tried 2017.3.0b5 this morning and all my editor stuttering was gone. Going back down to 2017.1.2p2 to see if its also working better, if so I'll skip 2017.2 altogether, its a mess.

 

Yeah, I'm really regretting upating to 2017.2. UI is a complete mess. RectMask doesn't work, ContentSizeFitter memory leaks, TextMeshPro issues. Vuforia integration is horrible.

Hope there's a patch release within the next 2 days.

I'd like to move to 2017.3, but feel that's too unstable as well, especially for a submission I have in 3 days.

 

Still no luck with 2017.3.0b5

 

Migrate To Unity 2017.2F3 and same issue with RectMask 2D that does not work now. Submission IOS today
