    Subapplications - tearing when scrolling

    For some reason I always get poor scrolling with tearing in subapps. If I run my project as a regular application, it scrolls nice and smooth at 60fps with vsync. But as soon as I make it a subapplication and launch it from my main application (which is real basic - just a simple hub mainly with a few graphics), it scrolls terribly with lots of tearing. The main application has the same graphical settings as the subapp and I'm using the latest build of MMF2. It does this on both of my PCs, but I did a search on the forums and there doesn't seem to be anyone else mentioning this issue which I find odd.

    I'm just curious if anyone has noticed this or am I the only one.

    Re: Subapplications - tearing when scrolling

    Did you check the "Clip Siblings" checkbox, on the Sub-Application object's properties?

    I've found that it helps correct some wired graphic problems when working with sub-apps...
    Anyways... hope I could help


    Good luck!

    Yeah. It didn't make a difference.

    Maybe providing an example would help here?

    That way, we can see what is happening and if it applies to everyone's computer.

    Re: Subapplications - tearing when scrolling

    I took a look and I think it's due to the way sub-apps are handled in MMF2. As the handling routine is not separated from the display routine, the current frame loop of the sub-app is executed in the display routine of the sub-app object and that takes time. It's not easy to fix in this version of MMF2. Maybe we can fix it in MMF2 HWA, but I'm not 100% sure.

    Or maybe I can find a solution to handle the VSync option directly in the sub-application object...

    Re: Subapplications - tearing when scrolling

    Alright then, thanks for the info Yves. I guess I should start thinking about a work around for my game then. I wanted to avoid using seperate executables for the main title menu, levels, etc. as it's a bit sloppy. I guess the only real alternative is to just put everything in one application. The game is enormous though, so I'm not sure how well that'll work.
