UI interactables with multi display not working
Hello,
I've tried setting up multi display UI but I cannot get the buttons/toggles/dropdowns to work on the secondary screen.
I have enabled the multi display, and I'm instantiating a canvas + camera prefab for each display, it renders just fine, but any interactable UI elements freeze up upon interacting. I can control those UI elements from my gameManager scrip just fine, but the actual "interact" part does not work. The elements gray out, and never recover.
I have tried instantiating this canvas + camera on the display[0] and that works just fine, its only display > 0 that breaks the UI.
I tried looking into it online, and everyone says the buttons on multi display were broken in Unity 5.3. I'm on unity 2020.2.7, which is waaaaay past 5.3.
I can provide more info if necessary.
