Previously before updating to 5.4 our projects built for WebGL used the loading bar code found at: Unity WebGL Custom Progress Bar - Alex Ocias Blog this code gave us a smooth loading bar.
However after updating to 5.4 our WebGL builds with no change to the UnityProgress file now result in a jumpy/unresponsive loading bar that doesn’t work like it used to.
Has anyone had similar issues or does anyone have a working smooth WebGL loading bar that works in 5.4?
