    Rendering slowing down over time - Help - Chip 8

    Guys I'm about to finish a chip8 emulator written in C++ on c4droid ( a C11++ and SDL IDE for android)

    So far a lot of things are working such as counters, renderer, timers and input handling, but I'm getting a strange behavior while running it.

    At first it runs at a good speed, but slows down over time.

    Things I have tried:

    1) Looking for objects created while on the main loop
    2) Freeing all surfaces as soon as i'm done with them

    My rendering function consist of just drawing SDL_Rects on the screen. And I'm only updating the screen every 10 opcodes
    I'm not doing any Clear rendering in between updates, I also create button objects once per activations, and the buttons get filled and outline draw on demand... can multiple fillrects/draw rects be really slowing down the emulator that much?

    Thank you in advance guys
