Bug UGUI Canvas keeps re-scaling objects while editing

Testing out 2019.3 and having some issues while setting up a UI. As I edit the UI in the scene window it keeps scaling the objects in the canvas. Its like its changing the resolution, but the objects are remaining the same size like its not maintaining the reference resolution but the positions remain the same. It's makes it very difficult to work with the UI in the editor.

I am using LWRP version 7.0.1 with 2019.3.0a12.

 

Unity staff is probably going to ask for a bug-report. If you want to speed things up, I recommend to submit a bug-report as explained in this document:
https://unity3d.com/unity/qa/bug-reporting

... and post the bug-report case number here for them to pick up.

It's important that you report these issues together with a reproduction project if you want them to get fixed. If you don't do it, it might be a long time until someone else reports them or until Unity Technologies find them.

 

I will create a repo project and submit it once I have a chance.

 

When trying to create a repro. Brand new project, installed LWRP and I cannot create the asset to use LWRP in the project.

The only option under rendering is Universal Render Pipeline. I can create a pipeline asset from that and use the new 2D renderer. Not sure if this is an intended change or typo or if this even is the LWRP. I've looked at my other project and noticed it has the same thing.The other project was started in 2019.2.0 so it showed up as LWRP.

After a bit of messing around, it seems its the Canvas Scaler set to Scale With Screen Size is the problem. Disable the canvas scaler and no more problems.

So I submitted the problem with Case 1179114.

 

It's an intended change:

Here is the LWRP to Universal RP upgrade guide:

Thank you @Peter77, hope they get these things ironed out. 2019.3 is looking great, love the graphical changes to the editor and all the wonderful additions to Unity in general.
