Ahhh, finally! Thank you, man! Now I finally understand why is it working sometimes and sometimes not. That depends on the monitor! Even this knowledge is fantastic

And hope that developers will fix that soon.

Phew! I was worried my studio was the only group setting this bug. Glad to hear it’s getting some traction, because we’ve got some pretty bad heartburn with it.

After a lot of attempts, I’ve been unable to get this issue to reproduce, also using the provided reproduction project (that I deleted because it contained all of Odin in it). I am using dual monitors in a normal setup, on Windows 10 and Unity 2019.2.19 as well as 2018.3.11 (both essentially the same as is reported). No amount of clicking around in either window gets this to break, for me, whether I drag over the entire “main” editor window or pop out a smaller “sub window” and drag that to another screen. Nothing I do reproduces.

Are any other strange screen effects or UI scaling solutions, custom OS screen modifications, or anything else like that active on your computers? That sort of thing is the only thing I can think of. And in the case of UI scaling, Unity’s window handling has serious issues with UI scaling that I believe we once determined we could not fix or do anything about.
