    VR Chat is also using this unity version which I am sure they know about. But the Dev's don't seem to acknowledge the issue.

    So 10 months after it was reported, this is still listed as a known issue in 2018 LTS?

    2018.4.23 - fix still not available there...
    I'm pretty sure, that I saw a resolution note for 2018.4.23 here, but it disappeared.

    I beg you Unity, please fix it in 2018 LTS

    2018.4.22 and this still isn't fixed.

    The guy assigned to the task marked it as solved. We may have to open a new ticket for anyone to look at this again.

    Is this bug reproduced on android build too or only windows standalone ?

    You'd think the LTS versions would get priority patching.
