Play mode maximize not like 2020.1.6 version


I updated Unity Editor to 1.8 (of 2020) and badly, I see that the maximize feature for play mode isn’t like the old version (1.6) where I saw all the mode on my window.

See what I have now :

My play mode, also in maximize feature, have a grey background, before the mode was on all the screen. I don’t know if it is a problem from my settings or a bad new update …

Hi !
I found the solution :

In “Game”, select the aspect of your resolution. After, uncheck “low resolution aspect ratios” and select “free aspect”.
