jerky gnome on debian only with nvidia driver.

im currently switched from jessie to stretch and on both i notice a weird jerky gnome feeling when using the nvidia driver. also when i run chromium, gnome videoplayer or minimize a game and move a window on desktop at the same time, my xorg cpu load goes close to over 80% on core 1 of my cpu.

with the nouveau driver i dont have any of this problems.

daniel@Daniel-PC:~$ glxinfo | grep rendering
direct rendering: Yes
    GL_NV_parameter_buffer_object2, GL_NV_path_rendering, 
    GL_NV_parameter_buffer_object2, GL_NV_path_rendering,

xorg log:

drivers i have tested: the driver from the debian repository, the current beta and final driver from nvidia. currently im using the one from the debian repository.

nvidia gtx 760
intel xeon e3-1230v3
8gb ram

edit: as it seems im not the only one with this problem:
