This really happens with any minecraft version. If you ask me, the priority must be "Important". As the title says. Even if we go to "javaw.exe file > Properties > Compatibility" and we check "Disable fullscreen optimizations" it results into a borderless window with DWM's vsync ON, and a lot of stuttering and input lag (it can be partially fixed by enabling ingame VSYNC, also it adds a lot of mooore input lag). With integrated GPU it works as expected (and I'm forced to use this to get a good experience). Other OpenGL games can enter into fullscreen mode (LWJGL based games also), so it isnt a driver or related fault. I think the issue is with Minecraft.

I waited for several time (like 2,5 years, no joke) and its still happening. Minecraft Java + NVIDIA Optimus system is unplayable. Only this game.

Please fix it.
