Windowed vs fullscreen MonoGame 3.6 stuttering (fixed)

I’ve recently began working on a project again using MonoGame 3.6 (cross platform using OpenGL). I recently have this weird problem where the program stutters (ex. moving an object across the screen) in windowed version and not in fullscreen (even with an almost empty project).
There is no stutter when launching the project in fullscreen, but there’s always some stutter when it’s windowed. I’ve tried several things like changing vSync or IsFixedTimeStep to see if it fixed the problem but it did not.

I did not find another case of this online. Does anybody know something that can cause this?

UPDATE: Seemed to be an intel problem. Windows in Windows 10 were also stuttering. An intel display driver update fixed the problem.
