[Bug] Windowed rendering hangs when not focused (for splitscreen)

Current Behaviour

With Controlify installed, when the game is in windowed mode and focus is switched to another program or desktop (like another instance of minecraft for splitscreen play), after less than a minute the window will appear to freeze and not respond until you Alt+Tab. Clicking on the window shows minecraft is not responding, only using Alt+Tab brings it back.

In this frozen state, you can still move and interact with menus, but nothing is shown on screen. If I disconnect the controller, it unfreezes instantly. I am using the setting to enable control without focus, this seems unrelated.

Expected Behaviour

The window should not visually freeze when focus is lost. This only occurs with Controlify installed and a controller connected.

Screenshots

I can upload a recording to better illustrate the issue if requested.

Reproduction Steps

Install Minecraft 26.2 with Fabric 0.19.3
Controlify 3.2.1+mc26.2
Fabric API 0.156.0+26.2
YetAnotherConfigLib 3.9.6+26.2-fabric

Start minecraft in windowed mode, connect a controller, enable the control out of focus setting.
Focus another window or even the desktop, and continue playing for minute, the freeze usually happens within 60s for me.
