Objects disappear after intermittent time

Hi, I’m building up a 2D game in c++ with OpenGL, and recently I ran into a glitch with the objects on my screen all disappearing. This started after I updated my code to include 2 types of objects, an orb and a player, each with their own shader programs. The render function for my player object, given w as a pointer to my World object, is:

void Player::render(int layer) {
    glUniformMatrix4fv(w->proj2_location, 1, GL_FALSE, w->proj_matrix);
    glBindTexture(GL_TEXTURE_2D, w->texture[1]);

    glBindBuffer(GL_ARRAY_BUFFER, vbo);
    GLint posAttrib = glGetAttribLocation(w->scaleing_program, "position");
    glVertexAttribPointer(posAttrib, 2, GL_FLOAT, GL_FALSE, 0, 0);

    vmath::vec2 pos = {position.mX, position.mY};
    vmath::vec2 cam = { TheCamera::Instance()->point.mX, TheCamera::Instance()->point.mY};
    vmath::vec2 offset = (pos - cam)/100.0f;

    vmath::mat4 mv_matrix = vmath::translate(offset[0], offset[1], 0.0f);
                            //vmath::rotate(0.0f, 0.0f, 0.0f, 0.0f);
    glUniformMatrix4fv(w->mv2_location, 1, GL_FALSE, mv_matrix);

    GLint rl = glGetUniformLocation(w->scaleing_program, "r");

    glDrawArrays(GL_TRIANGLE_STRIP, 0, 4);

my other object is very similar; Am I missing something?? The objects disappear usually after about 15 - 30 seconds on the screen, but appear fine until then…

I guess my OpenGL code is alright for now; I found an issue with seconds passed being 0 on occasion causing the glitches.
