I have a global renderer constant which I use for both. So I'm sure it's the same renderer. However it returns RenderTexture instead of Texture (as graphics.generateTexture()) does. Is that significant?
Doesn't seem like there's a proper way to find out if the browser is zoomed in anymore. Damn. I don't understand why the browser wouldn't let you control that. Ok, maybe not all the time to avoid shenanigans, but at least on redirect.
@ivanpopelyshev Yeah, your solution does actually work, provided that the browser window is maximized. Unfortunately, I can't rely on that. Plus, I have some absolutely positioned html mixed in with pixi, and IT goes out of whack when I zoom.
