    Hi everyone,

    I recently released a game to production and encountered a strange glitch occurring only on particular menus and particular Android devices.
    I was wondering if anyone has seen anything similar to this and might point me in the right direction as to how I can fix this, right now I haven't the slightest clue where to start debugging.

    Below are screenshots of how the screens are supposed to look:


    and here is how they look to the users experiencing the glitch:


    So far the only similarity between the two pages are their use of scrollable containers (with masking).

    The devices with this issue reported are:
    1. Nokia 9
    2. Redmi K20 Pro

    I have this exactly glitch on some devices. Testing lots of little changes to find the problem right now.
    Will reply again if I find the issue.

    I resolved a similar problem (not identical) by removing the ScrollView Viewport's Mask component then adding new component Rect Mask 2D.

    I'm alredy using Rect Mask 2D.

    Eliminated the glitch already and I'm trying to discover the real cause. I'm creating a build right now. My suspects are on "Blit Type: Always" insteady of "Auto" on Player Settings > Resolution and Presentation.

    Let me test it and I'll reply.

    Edit: it was not... more builds now.

    Guys, did you find anything? I'm already low on reviews and this glitch is causing my ratings to go further down. Please help.

    Hey guys, OP here. I totally forgot about this post but I finally managed to pinpoint the issue after alot of debugging - turns out the font package we were using didn't contain the symbols for certain currencies (this bug happened on any page that had pricing displayed).
    Seems when it tries to display a font symbol that the font package does not contain this happens.

    Hope this helps!
