Interesting. Could you check the debug console for me and see if it caught some errors? On my end (firefox and chrome) it works exactly as intended. Perhaps it has something to do with the operating system or the render piepline. I have compiled it on linux and used the universal render pipeline for the first time (in retrospect this wasn't worth it).
I noticed it that some games don't run on my system, but run fine on others. This is peculiar indeed.
