I have a web game with a drag and drop menu, the menu buttons are pinned to an invisible sprite with drag and drop behavior. It works fine when I test it on different computers and browers, but some users have reported that the menu items are invisible.
When I experimented, I tried turning WebGL to off instead of on, and then the menu was invisible for me too. So I guess those users computers can't use WebGL or something like that?
I discovered that the menu buttons are not invisible if they are on the top of the Z order in the layer, but the thing is that I have a mask on either side of the menu (invisible sprites with "source in" effect, and I need those to be on top in the Z order for it to mask the menu properly.
Any advice on how I can make it work for those without WebGL support?
