If the discrete Nvidia GPU is active for Illustrator, then outline mode does not work.
Expected result: selecting outline from the view menu (or using ctrl+Y) will change the display to outline view, and then toggle back again.
Actual result: The displayed image becomes unresponsive (e.g. cannot pan, zoom) and does not change to outline view. The menu item (view>outline) text changes to read 'GPU preview CTRL+Y', which is directly above the actual GPU preview toggle (CTRL+E).
If the the GPU is set to integrated, the program behaves as expected, with the exception of the menu item text changing in this instance as well.
I have only encountered this issue on a laptop with discrete and integrated GPUs - it has not happened on a desktop without integrated GPU.
