Hi all,
When I try to load the Unity-6 WebGL build, a black screen appears 4 to 10 seconds before the Unity logo appears. There are no root causes for this delay that have been found when investigating this issue. Could you please tell me who can short this issue or given any guidelines to handle this delay issue.
Generally WebGL loading will be slow. If it’s an empty project it shouldn’t take this long, but it could (first launch) and it may depend on the system and browser.
If you have content in your project a loading time like this is quite common, especially if you have not carefully optimized assets for use with WebGL.
Also Player Settings may affect build behaviour, it can make a huge difference whether it is a DEBUG or RELEASE build. Most importantly is the HTML template, you may want to try the minimal template.
If it happens to be a regression, ie the same builds with 2022.3 load much faster you should send a bug report.
