Whenever I used F10 or Shift F10 to increase/decrease graphics quality, the new value that is display in the notification is sometimes incorrect (usually off by 1). Ie. I change my graphics from 10 to 9 using Shift F10 and it says that my new graphics quality is 8, even though I only pressed the keys once and my Roblox settings says my graphic quality is at 9.
Here’s a video of it in action (make sure to look at the Roblox settings graphic quality aswell as the notification; you may need to slow down the video!).
You will also see if I fiddle with it, it will be offset by 1 until it reaches either 1 or 10. Like it will say “increased to 5” after increase it to 4.
