    I'm having problems with my UI when I mouseover my buttons or anything else that has a sprite change. The weird part is that it will affect other sprites that don't have any kind of mouseover action.

    This video explains it all, any help here?

    What version of unity are you using? There was a bug we fixed where sprites that had no texture assigned would use the previous rendered texture. This should be fixed in the latest but a simple fix is to create a simple 1x1 texture that is white and use this instead of no texture.

    I'm using 5.3.1

    I replaced all sprites that were empty and it seems to still be happening, but it doesn't draw the last sprite anymore. It will now draw a text atlas in the sprites place. Is there something I should be doing to the font file?

    No it sounds like a bug. Is it 5.3.1p1 you are using?

    Yeah p1, it only happens with sprite swap but I don't see how it affects other sprites that aren't buttons.

    I've met this issue too. Maybe that was occred when gameobject with text and image are instantiated at runtime,

    And i have another question.. when the z-axis-value of a Text component is changed to a non-zero-value, the drawcall value displayed on stat window( which called batches after U5 ) grows obviously.
    I've reported this issue before, the issue id is 746840
    Thanks for your great work..

    Have you tried the latest version 5.3.3f1?
    If it still has problems please submit a bug report with a sample project.
    Thanks.

    I'm having this issue now also, though it manifests in a different way. Sprite sheets and text randomly corrupt. Appears to only happen in release builds from what I've seen so far. Though it may be machine dependent. I'll be running some more tests to see if I can get some more specifics.

    Using version 5.3.3f1

    This is concerning as the game is due to ship soon.

    ...Life of a programmer

    Edit:
    Problem occurs on both AMD and Geforce cards, so maybe it's not machine dependent.

    Are you on a mac? There were OpenGL issues which should be fixed in the latest patch.

    I am using Windows machines and release builds.

    I think I may have figured out the problem.

    The game's chat window was using the outline script. When enough text filled the window (not much), a 65k vertex limit error was generated and the window stopped displaying the text. That's fair behavior. What's unexpected though, is that various UI elements start to have texture corruption after that, like game pieces displaying the font texture, so I think Unity is just not preventing memory corruption when that error occurs.

    This is just a hunch though, as I've not seen the corruption since fixing that bug.
