Rect Transform tool handles sometimes become ungrabbable



How to reproduce:
1. Open the user's attached project
2. In the Project window enter "New Scene"
3. In the Hierarchy window select Canvas->GameObject
4. In the Scene window try to grab Rect Tool handles and resize the Game Object

Expected result: Handles are clickable
Actual result: Handles do not react to being clicked on

Note: Double-clicking on "Canvas" or "GameObject" fixes the issue

Reproducible on: 2018.2.0b3, 2018.2.20f1, 2018.3.1f1, 2019.1.0a12
Not reproducible on: 2017.4.17f1

    Resolution Note (fix version 2019.2):

    We are unable to reproduce this error from the dev side. After talking with QA who accepted it, resetting Unity's layout corrected the issue.

    This is happening to me right now in 2019.2.0b7 and has happened occasionally with earlier versions as well.
    I'm sorry you can't reproduce it, but the problem is real, so maybe more effort or patience should be put to hunt it.

    Can confirm this issue still exists in 2019.3.0a7. "Resolution" as noted worked for me: double-clicking a UI GameObject allowed me to use the Rect Tool again everywhere in the project. Not sure if related, but this issue occurred for me on a dual-monitor set up (one 4k one 1080) after dragging the game window around between screens.

    Someone on my team figured out that by setting Layout to Default, it fixes this problem.
    We don't know why. But it's a consistent fix.

    Started happening from one day to another. Didn't change a thing in the whole project.
    Now I can't work.

    i found that when probuilder is installed and you have accidently clicked to activate the vertex, edge or face selection tool. it disables the rect transform and other tools on the top bar.
    Changing probuilder back to Object Selection, fixed this for me.

    The Q/A team specifically noted what versions are effected and reproduced the issue in all of them. You can simply open the project and see that the entire rect tool no longer functions. Several users have experienced the same issue. Curious how this was marked not reproduceable?

    Issue started earlier this year. Sometimes goes away but then comes back. The entire Rect transform tool stops working, so you can't move object's locations or change their size using the mouse. Tried exporting and re-importing objects, removing and re-adding to scene, deleting and re-creating prefabs, no effect.
