Unity 2019.3.0b3 and 2019.3.0b4 memory leak? Menus opening wrong windows

After I press Play in Editor, all menu items open wrong windows or execute wrong code. For example Window -> Animator opens Profiler, sometimes even crashing the Editor

Did anyone else experience this?

 

Nope, not happened to me yet.

 

Here's an example:

 

Haha, that's pretty crazy!

I once had something that completely corrupted Unity in a similar depth.
If I touched a certain Unity variable (like, just read its value), the entire Editor would get randomized. All windows would have random sizes and fill the entire screen. I imagine some stack corruption was happening in the C++ side.
I could never submit a repro because it only reproduced on some machines.

Maybe a simular corruption is happening in your case.
I just tested here, and it works normally, so it might be code or computer dependent.

Are you doing anything special when entering playmode?

 

Found the issue, it was this plugin: https://github.com/SubjectNerd-Unity/ReorderableInspector

 

Maybe open an issue report there so the maintainer can investigate where the corruption is coming from.
