DMGregory guided me towards a good solution explained in this article:
Use a fixed timestep
This solution allows the total decoupling of the simulation and rendering frequency, while allowing for a fixed timestep for the simulation part.
Visual smoothness is preserved by interpolating between the previous and current (last) state of simulation with a ...

The equation of motion under constant acceleration is:
$$\vec p (t) = \vec p_0 + \vec v_0 \cdot t + \frac {\vec a} 2 t^2$$
So if you didn't have your drag, you could modify your code like so...
if(button_pressed) vel_x = run_speed;
else // TODO //
pos_x += vel_x * dt;
pos_y += vel_y * dt + 0.5 * gravity * dt * dt;
vel_y += gravity * dt;
...
