1. Open the attached project (
2. Enter Play Mode
3. Select the "Main Camera" GameObject in the Hierarchy
4. Press the "L" key on the keyboard to lock the cursor

    Yes upgrading to 2021.x solves this but yeah would be super helpful to have in the 2020 LTS releases as bitpixel says.

    +1 on this, also happens on 2020.1.8f1. Are there any updates on this? I opened a similar issue on this one 2 months ago and was directed to this with the state "fix in review", but now it's back to Active?
