Unity 6000.3 also tested with unity 2021 same problem occurs
using bytebuffer, same problem happens with hardwarebuffer.

I apologize for the late response. Thank you for the report. I would like to know a little more about the issue. Does the screen freeze when you switch to full screen? If so, I imagine that the browser instance may have crashed due to a memory error (I have encountered a similar issue before). Please check to see if the problem is resolved when you lower the resolution of the browser instance (line 1024x1024 → 512x512).
