What is OSR mode ?

Hello

What is OSR mode ? and when we need to use it ?
I saw in the comments that in windows it is desactivated by default

When I set OSR mode to true on windows the renderer of the windows is different (smaller police) but there is less java shutdown

Thx in advance

anyone please ?
I don't understand why with the OSR activated, the font size change ?

OSR means off-screen rendering. The browser is rendering web content into a bitmap that is then rendered by the client, instead of the browser creating and managing its own window.
