I am looking for a way to reset the player window to the actual size of the video being played. This could be implemented as an item in the ‘Video’ menu.
Currently, the only way to accomplish this is to full-screen the resized player and then exit out of full-screen while the video is playing. The player reverts to the pre-full-screen dimensions first, and then, a second later, reverts to the actual video size, which is clearly an annoying bug.
