Bump, I really need this fix on the LTS version. It would be great to have it.

I just wanted to bump this again. Will we ever see this in LTS version or is all hope lost? It would be great if this matched the behavior in Android version.

I fixed it at 2018.4.23 by add some code in UnityVIew.mm like 2020.1.17f1c1 do

Just wanted to bump this again. Any chance this will be fixed in 2019 LTS?

With 2019 LTS release out, it would be amazing to get this in there. Is there a plan for this?

As a temporary fix, I found that changing the antialiasing setting in the Quality Settings makes the resolution scaling update for some reasons

Someone on forum tells that the resolution changes when you restart or enter background mode of app and then has returned back and it will apply the changes. But not realtime, yes.. so.. it is not the case ofcourse.
