my build works if i build for pc, but when i build for webgl, with same resolution, my ui doesnt show up on the screen at all. i even have a non ui sprite in front of the camera, and it doesnt show up either.
i cant reproduce the problem in the editor at all. no matter what crazy resolutions i set, it only happens with webgl.
i think the ui is just not being visible, because i would click around on the screen and it would trigger a button, which loaded the next scene, and then the ui was visible.
edit - i tested more and ui is definitley there, just not visible. i can click the invisible buttons to go to my next scene, which works. and going back to main menu again gives same problem.
