    Hi

    I have currently just updated my version of Unity from version 2020 to 2022.

    After checking the size of a build of one of my games, I realized that there was an upward difference with the new version.

    The build logs that I have been able to consult show that a line has been added in the 2022 version which would roughly correspond to the difference:
    - 2.7 mb 15.8% Built-in Texture2D: Splash Screen Unity Logo

    Is this a bug?

    Thank you in advance for your answers.

    Not a bug. The 2+ mb size of the logo is the actual size I‘m afraid. Only if you pay for Pro you can get rid of it.

    Hi,

    Damn! I really thought it was a bug. This will waste valuable build space.

    Thank you for your reply.

    Good day.

    I'll flag it with the team looking at optimizing web builds as something to look into.

    Note that the build log displays uncompressed asset sizes. In Web builds (like on many other platforms that Unity supports), all assets are compressed with LZ4HC compression, and on the web, also double compressed if you set gzip or brotli as the asset bundle compression.

    So the actual size taken by the splash screen on disk, or transferred over the web should definitely not be as high as 2.7MB. Estimating, I would expect some 100-200KB at the moment.

    It is not the intention of the Web Platform team that users should need to get a Pro license to get to the smallest builds, so this is being treated as a performance bug at the moment to see if there is room to squeeze the file to be even smaller on disk after compression.

    Even when Pro/Plus users disable the Unity logo and/or splash screen, still get on an empty project:
    1.2 mb 52.8% Built-in Texture2D: Splash Screen Unity Logo

    It's not much, and not much after using brotli, but it is still there, and trying to cut any excess weight, it'll be nice to be able to remove an asset which is not in use.

    Should I open a bug? @jukka_j @brendanduncan_u3d

    Closing the editor and re-opening cleans the logo texture from the memory, then it doesn't get into the build.
    So it's an issue only if you build with the logo, and then remove.

    Sharp find @De-Panther.. definitely would be great to have a bug. That does suggest some kind of mismatch that the Editor does not realize to rebuild the project after changing the Splash Screen checkbox.

    The bug will likely go to the Asset Database team and not to the WebGL team, so would be good to track that through so it gets to the right team.

    Paying for pro doesn't remove the logo unfortunately. You wont see it but it's still forced into the build.

    Read my 2nd comment, try to close and open the editor, and see if the logo still enters the build
